[biofuels-biz] A nice story
One of my customers for biodiesel is a musician. He decided to build a new recording studio behind his house. First job was to excavate for the foundations. Being a Brit. and careful with money, he hired a small digger and had 6 friends come round with wheelbarrows to shift the surplus earth. On the first day, they all complained about the choking diesel fumes from the digger. The second day, the musician syphoned biodiesel out from the tank of his car and used that to re-fuel the digger. The 6 friends were very happy (but still complained that they felt hungry). The digger didn't seem to notice any difference. True. David T. Yahoo!

Good. Free copy of DIN EN 14214 found and translated by AltaVista Babelfish from http://members.dokom.net/torsten.kiebert/html/dinen14214.html As well as iodine number (which is a proxy for degree of unsaturation), there are also limits for the percentage of linoleate ester and for esters of fatty acids with more than 3 double bonds.

Re: [biofuels-biz] Fwd: [biofuel] Mixing times for complete reactions- was Re: Max capacity
Pannier, Hydro-cyclone separation is a good idea in principle. From my experience with these, I should think you will be looking at a bank of several small diameter units manifolded together on all three pipes (inlet, apex and vortex finder). If these are above the reactor and uninsulated, the mix will cool and help the thermosyphon to keep going. Power from a solar collector can be pretty good in bright sunlight (e.g. 0.5 kW/sq. metre) so it is not an impossible dream at all. Remember that once up to operating temperature you need a heat sink as well as a heat source to get circulation. The head loss in skinny cyclones might be around 0.5 metres, and this added to other pipe friction and entry/exit losses means you will need quite a tall structure to get a powerful thermosyphon flow. Glycerol-rich mix will drop out from the apex as underflow. The question is; how to get the best balance between removing glycerol (which inhibits transesterification) and removing catalyst along with the dark stuff? I suppose trial and error is a reasonable approach if you have plenty of sunny days. The underflow will also contain alcohol and esters. These will have to be separated by gravity and distillation for return to the next batch. We are interested to design the use of solar enegy instead of wood as fuel and looking for the innovative design. Is there any one who already have done this design for recirculation using thermo siphon without pump , solar heating, product separation on the top using cyclone and recirculation of catalyst.Will this method useful compared to conventional method.

Re: [biofuels-biz] Fwd: Biorefinery projects take first steps
Quite impressive by the American funding agencies. One reservation though: The project's goal is to develop catalyst systems and a continuous process to produce isosorbide from sorbitol and to support a scale-up of the process, purification and recovery, and pilot plant operation. So are we heading for huge factories with feedstock being hauled large distancesagain? Another intersting snippet I came across recently: The oil to be esterified must be extremely dry and low in free fatty acids, peroxides and any other material that may react with sodium methoxide. A few minutes after the catalyst is added, the oil acquires a reddish brown color due to the formation of a complex between the sodium and the glycerides. This complex is thought to be the true catalyst. David T. Yahoo! Groups Sponsor -~-- Buy Ink Cartridges or Refill Kits for your HP, Epson, Canon or Lexmark Printer at MyInks.com.

Re: [biofuels-biz] USING SEPARATOR FOR AFTER WASH TREATMENT OF ME
So, the old question of centrifuge vs. straight gravity separation has re-surfaced. I had dismissed centrifuges for various reasons, but would still like to speed things up. One action I have observed is that when misty ME is left to settle in a glass cylinder, a lot of the water is attracted to the side walls rather than the bottom of the vessel. Once on the sides, small water droplets coalesce and fall to the bottom. The same is not observed in metal or HDPE vessels. My speculation is that because the water molecules are polar, while the ME is non-polar, and the glass is electrically non-conducting, then a static electrical charge on the cylinder attracts the water. If this is true, it is left to devise a way of charging a larger non-conductive plastic vessel (inside +ve, outside -ve or vice-versa) and we have the makings of a nice quiet but effective process :-) By way of caution, I still harbour a suspicion that clearing may be due to peroxidation stimultated by daylight, and that the observations could have nothing to do with electrical charge.

[biofuels-biz] Where did 3.5 come from?
I was intrigued by the contribution of a few weeks back and copied below. So I checked back to Mike Pelly and others recipes. No sign of why 3.5g/l is the amount of NaOH needed for biodiesel (over above ffa neutralisation amount). Can someone elucididate please? Keith, quoting Todd on 7th August said: Most of us who have performed straight base reactions titrate in order to determine how much compensation must be made to override the presence of FFAs. And most of us have relied upon the 3.5 grams NaOH + x formula. The really fanciful part that few people have given much thought to in the backyard biodieseler's environment is that catalyst is never destroyed. It may get bound up, such as with FFAs or particulates, but if both of those variables are compensated for, the remaining free catalyst is there to do its job. So...define the purpose of a catalyst. Essentially adding extra amounts of catalyst accomplishes virtually nothing save for reducing reaction times, as catalyst is not destroyed. Essentially, even in a straight base esterification, it should only take a gram or less of catalyst beyond the titration requirement to effect a completed reaction over time. The biggest problem is that few people want to take the time. One-half gram of catalyst under heavy agitation might take 24 hours or perhaps even longer to convert 1 liter of oil. But the beauty is that if only one-half gram is used, 3.0 grams are omitted in comparison to some of the tried and true methods in the biodieseler's bibles. If you can get rid of this amount of base, you can also get rid of a relative amount of acid neutralizer, whether it be in a water wash or the FFA recovery from the glycerin layer. But the primary benefit of base catalyst reduction to the lowest possible level (lowest possible level to meet specific demands) is the reduction of soap formation. Yes, the base is a catalyst. But yes, it also saponifies triglycerides - it is conducive to making soap, even in the absence of FFAs. The primary trick is to get rid of the FFAs, thereby reducing the volume of excess base catalyst needed for compensation, then create a system where time is not the most important element...where the method of manufacture and the energy comsumed to create ester manufacture is at a minimum and in balance with the least possible amount of catalyst appropriate to the specific application. If this is 15 gallons expected to react completely in two hours, the catalyst requirement will be heavy, and so will the soap manufacture. If this is 500 gallons expected to react completely in only 24 hours under heavy agitation, the catalyst requirement can be minimized to extremely small levels, which will in turn reduce soap manufacture, and in turn, reduce wash problems.

Terry Lohnes' original post reported that : Right now, I'm experimenting with separation of 80% soybean oil, 20% water (emulsified in a blender) using a CaCl salt solution at varying concentrations and temperatures. My concern is that this is not representative of typical water contamination percentages (more like 1 to 3%) and that there may be an effect analogous to the famous azeotrope when distilling ethanol.

Re: [biofuels-biz] The Hydrogen hype, the scam artists at work.
Hakan, Your perspective on hydrogen is probably right and needs saying in public. You make comparisons with gas from coal. I remember in the days before methane was discovered in the North Sea (known as 'North Sea' gas rather than 'Natural' gas here in Britain by the way), and most towns cities had their gasworks sited near the railway, canal or navigable river bringing in the coal. In Britain, the Commonwealth and elsewhere the product was known as 'Towns gas' rather than 'City gas'. The carbon monoxide content made it more toxic than methane. Apart from the points you made, these old gasworks are among the most polluted sites in the land, with naptha, phenols, tars sulphur compounds still in the soil, long after the bad egg smells have gone away. The same would apply to gas from biomass (or turkey guts), though with modern pollution abatement methods I suppose it can be kept under control. An interesting side note was that tar from the gasworks was used to surface roads at bus stops because it does not soften in the oil dripping from bus engines. At a meeting a couple of years ago, a delegate suggested that the best policy for global warming would be to burn all the world's trapped methane before it escaped into the atmosphere. Then there is the issue of methane hydrate on the sea bed.. Dvid T. Yahoo! Groups Sponsor -~-- Get A Free Psychic Reading!

[biofuels-biz] H2 from glyc.
Here's an interesting clip from http://www.eere.energy.gov/hydrogenandfuelcells/pdfs/25315hh.pdf Results In earlier work we reported the ease of gasification of glycerol in supercritical water.Table 2 confirms the earlier result.In it we see that the hydrogen content of the gas increases from 38% to 51 %after 3.45 hr,while the methane content decreases from 20%to 11 %.During this time the total gas yield increased from 1.18 to 1.6 L/g and all the carbon in the feedstock was converted to gas.The increasing gas yield is due to the consumption of water and methane by the steam reforming reaction.Evidently this reaction is catalyzed by the reactor's wall and/or the carbon catalyst,which become more active (i.e.seasoned)as time passes.When the gas yield reached a steady state,the feed was switched and sawdust paste was fed to the reactor for 4 hours.After this,glycerol was again fed to the reactor.Table 2 shows that the sawdust paste causes the reactor's wall and/or the carbon catalyst to lose some activity towards the steam reforming reaction. The waste product generated by the commercial production of biodiesel fuel contains glycerol and methanol.We prepared a mixture of these two alcohols with a composition identical to that of the industrial waste.The gas produced from this mixture (see Table 3)is very rich in hydrogen,and the yield (2.05 L/g)is high.The water leaving the reactor was clean with a pH of 4-5.Evidently,this waste product is a perfect feedstock for hydrogen production.

The eventual application of ultraclean systems will hold tremendous value to a nation whose greatest fossil energy resource is coal. Parallels here surely with the hydrogen fuel debate where near-term opportunities for ghg reduction are foregone on the premise that something wonderful is just over the horizon. David T. Yahoo!

Re: [biofuels-biz] ethanol biodiesel
Daniel, I think you will find that water has a greater affinity for ethanol than it does for quicklime (CaO), so you cannot rely on this to absorb unwanted water from the mix. It has been used for neutralising FFAs. Try an archive search on 'another way'. I don't really know the answer to your other question, but your suggestion that the single-phase product might be diglyceride is superficially attractive. Probably there would be monos and tris present as well. There are tests for this if you want to get serious. David T.

Re: [biofuels-biz] bubble drying- big correction
Mark, When you raised the bubble-dry issue a few weeks back, I wasn't convinced that the main action was necessarily water evaporation. I tend to store samples of biodiesel in capped 2 litre Dr. Pepper style plastic bottles, and had noticed that if an air space is left above the liquid, it always reduces in volume, partially collapsing the bottle. My surmise has been that a oxidation process was at work, where the oxidation products are liquid, and the oxygen is removed from the air. I have also noted that if the sample strarted hazy, it would clear at the same time, not always with a preciptated residue of water or anything else. It would be interesting to test for oxygen depletion in the air pocket. I did try a rudimentary test to extinguish a burning taper (like we did at school chemistry lessons), but this was not conclusive. David T.

Re: [biofuels-biz] waste oil burners bu rning glyc erine,Ê ffa'sÊ
Tom, Mark, For comparison, my glyc. burner is a converted natural gas water heater from my brother's house. It started with one Babbington nozzle fashioned from a soup-spoon, with air supplied from a 12 volt tyre-inflating compressor. Enough ambient air is entrained by the atomising jet to complete combustion, but it can blow back if the wind is in the wrong direction. It now has an additional air blower to keep the flame front away from the nozzle. It runs very well on biodiesel, less well on pre-heated SVO, and poorly on pre-heated glyc alone. I tried mixing fuels in variable ratio using a tee-piece in the supply line, but adjusment was too critical. Next version will have 2 Babbington nozzles (probably tea-spoons), one for biodiesel and one for pre-heated glyc. The atomised spray jets will converge into the centre of the combustion tube. In this way the fuel mix can be controlled more easily, and the temperature can be brought up to a steady high value before introducing the glyc. Heat is removed by a pumped water circuit and transferred to WVO heating and meth recovery stills. With abundant heat, it should be possible to distil XS meth from biod as well as from glyc. There is then no dissolved meth in the washwater, which is otherwise a potential pollution hazard. David T.

Re: [biofuels-biz] waste oil burners burning glycerine, ffa's
Several contributors have spoken about drip plates. I was advised by a prof. of fuel science that dissolving 5% water in the glyc. would cause it to vaporise explosively on contact with the hot plate, so improving atomisation and combustion completeness. Obviously, you would lose the latent heat in the steam, but at 5%, that would be rather small. Anyway, it would be quite easy to try for those with a working furnace. David T.

Re: [biofuels-biz] butanol process and biodiesel biproduct
Thanks, Paddy. I always understood that the dark colouration was due to the FFAs. What do you reckon is in the by-product apart from glycerine, alcohol and a few salts? If oleic (and other?) FAs are soluble in esters, does this account for the variation in colour between batches (base-base process)? Are they water-soluble? David, I'm not convinced that the 'the mixture of FFAs and glycerol that combine in our 'by-product'.' that you mention does actually contain FFA. I recently aquired a sample of 95% pure oleic acid and found that it was completely soluble in biodiesel. Also, other FFA's will be solids which would be visible as solids as soon as the mixture cooled down.

Re: [biofuels-biz] Film on the ethanol issue in Australia
I have only limited experience of ethanol as motor fuel. Mine was hydrous (around 165 deg. proof) and immiscible with petrol. The car ran well enough after opening out the carb. jet, but the corrosion of metal and plastic components was very severe (just as decribed in the article). I have always ascribed this problem to the water content and assumed that all those Brazilians stay happy motorists because their fuel suppliers use A3 sieves. My suggestion, therefore, is to be sure the tests reported by the anti-ethanol press declare the water content of the blend under evaluation. Ethanol is hygroscopic anyway, so an actual measurement has to be made, and not a simple reliance on a supplier's statement. As for reports of knocking, this is most surprising given the high octane number. Indeed, most authorities suggest advancing ignition timing and/or increasing compression ratio to take advantage of this. In other words, engines are less likely to knock on alcoholic fuel blends.

Re: [biofuels-biz] Small-scale ethanol

No mention of either: *Its role as a greenhouse gas or *The loss of energy in all that carbon In one sense, fermentation is a cold combustion process so we are squandering a decent part of the energy in the original feedstock sugars.

Re: [biofuels-biz] Re: hi ffa feed stocks
One fact in common to all the recent contributors to this thread has been the bad effects of water produced in the acid esterification of FFAs; including saponification in the subsequent base transestrification stage. Most of us like to keep things simple, so I contemplate a boiling operation between acid and basic stages to evaporate the unwanted water. This would apply to our Scottish lard chip fat supply. The energy burden need not be too onerous using heat exchangers to recover some of the sensible heat (latent heat can't be easily recovered), and by using glycerol as heating fuel. I am a little worried about what boiling sulphuric acid (albeit dilute at this stage) will do to ordinary piping and vessel materials. David T. Yahoo!

My second point is that this forum is very concious of promising research into new and better pathways for triglyceride to ester conversion, so it would take a brave person to invest heavily in yesterday's technology.

Re: [biofuels-biz] Fw: RETROFIT ETHANOL VEHICLE
K. Vishwanath wants to devise dual-fuel capability for petrol 100% ethanol. I did this 2 years ago in order to use 170 proof (15% water) ethanol without the need to dehydrate it. This is good fuel but will not mix with petrol. My approach was to: 1.Fit a 3-way valve to the inlet manifold in place of the original carb 2.Onto one branch was fitted the original carb 3.Onto the other branch was fitted a similar carb modified for ethanol 4.Both carbs were linked to same throttle and choke cables so they opened and closed together 5.Vacuum advance tube was connected to both carbs via a tee piece 6.To change from petrol to ethanol, you simply rotate the 3-way valve so that the induction airflow is drawn through the other carb. Fuel is only sucked from the float chamber when air is flowing through the carb. 6.Modifications to the carb were radical enlargement of the jet orifice and replacement of rubber seals with nylon parts. Unsolved problems included corrosion of ali and steel parts, especially the float chamber, and finding space in the engine compartment. With modern vehicles mostly having fuel injection, the scope for this type of application is declining. The project was abandoned in favour of biodiesel, which has better economic ratios where I live. Yahoo! Groups Sponsor -~-- Take the Yahoo! Groups survey for a chance to win $1,000.

Re: [biofuels-biz] Digest Number 230
Tom's reply is very interesting. I have been looking at the Babington stuff too, and now realise that it would ideal for co-firing glyc. with bottled propane. The propane gas could be fed directly into the ball instead of compressed air, inter-alia saving the need for a compressor. I've not had a chance to try this, but suspect that some air would be needed as well to get the right balance of atomisation and heating value. So long as the gas pressure remains above the air pressure, it should be simple enough to meter gas into the air line. I intended to apply for a research grant on glyc. burning, and this new idea might be just the thing to hang the application on. What is the patent position? Going back to the Mother Earth drip-feed design, I hope to dilute the heated glyc with about 5% water, in the expectation that flash boiling of water in the droplets on contact with the hot plate will burst them into a finely atomised mist. David T. Tom wrote: I've been doing several postings on that other web site on this topic, so here is my input on this topic. The Babington burner works great for raw oil, ugly biodiesel, or other fluids, but it will not burn glycerol in concentrations greater than about 20 or 25%. It seems that this stuff is water based and just doesn't have all of the energy needed to sustain a flame. I had considerable success last winter in burning it on a wood fire, but by itself it would only burn the volatile part and then leave a substantial vegetable gum residue that did not burn. My current plan is to build a masonry burner that maintains the 1000 degree temperature needed for complete combusion. The Babington will keep up the temperature using raw oil and the glycerine will be dribbled into a pan where it should burn cleanly, leaving a mild residue ash. All of this is theory, but I have hope this system will work after 2 years of efforts. Tom Leue @ Homestead Inc. Yahoo! Groups Sponsor -~-- Buy Stock for $4 and no minimums.

Re: [biofuels-biz] Re: Vacuum
Motie, Youre on the right track with corrugated culvert pipe. I have done some work on resistance of pipes to external pressure, and have a design spreadsheet somewhere. Otherwise, you can find good guidelines from AWWA (American WaterWorks Association) for thin-wall pipe with external stiffening rings. The material is way off yielding in direct compression, but you need to restrain it against buckling. A cheaper and easier way of doing this is to select 2 concentric pipes of different diameters and fill the annulus with concrete. That sort of composite is very stiff, but you'll never lift it! As for keeping the vapour hotter than the liquid, your scheme will eventually overheat the liquid and either kill the yeast or denature the enzymes. Why not put a cooling coil in the liquid?

[biofuels-biz] Vacuum
Motie-d was asking about vacuum pumps, fridge compressors etc for vac distillation. One idea I have toyed with is inspired by the famous Magdeburg experiment where air was expelled from a vessel by boiling water in it. The steam replaces the air. When the vessel is cooled again, the steam condenses and there you have a very low pressure (vapour pressure of water at ambient temp). It occurs to me that the same could be applied to vac distillation by connecting a strong vessel (the steamer/condenser) to your evaporation chamber and controlling the pressure in the latter by a valve in the connecting pipe. I dont think there is any patent on this one! The condensing vessel need not be excessively large as, once the evaporating ethanol/water mix is at the desired temp press, the vapour produced is re-condensed in the reflux still so the net volume change is minimal.

Re: [biofuels-biz] Mother Earth News Waste Oil Heater
Had a good look at this with a view to burning glycerol (after recovering XS methanol). If anybody has actually built one of these, perhaps they will have some advice on how well it works..and on what fuel. Any temperature estimates? Combustion air is admitted via the pre-heating chamber on the flue, but I would be apprehensive about gases escaping in the reverse direction, particularly at start-up shut-down. Fan assisted air might help raise combustion temperature to avoid acrolein, but positive pressure in the furnace body is undesirable due to outward leakage of gases. On the other hand, a fan assisted flue would be very hot. Perhaps the best might be for a tall flue stack to gain a good natural draught. Any ideas before we start cutting metal? David T. Yahoo!

Tony, This is a common question with a multitude of answers, none of them very good at the moment. The main options seem to be: 1Sell or give it to craft soap makers 2Become a craft soap maker 3Consolidate your output with others and have it refined/distilled into commercial grade glycerine. This process is not practical at a small scale. There is also a danger that the market will experience a glut of glycerine and the price will drop 4Get the methanol out of it and compost the rest with other compostable biomass 5Burn it to produce heat. The problems here are that unless the combustion temperature is at least 600C, toxic acrolein gas is released, and there is a tendency to coke up the furnace components. My bet is that combustion in an appropriately designed and operated furnace is most likely to be the best plan. Somebody was working on a fluidised bed combustor which seemed like a promising idea, but news of that project has dried up. David T. Yahoo! Groups Sponsor -~-- Break free.

Hints of more efficient and less costly processes than the traditional NaOH/methanol approach should be taken seriously. Remember the porcine lipase thread of a few months back?

That is not to say it will stop working, just that it may become less competitive in cost, and hence be a 'stranded asset', in the way that coal-fired power stations have. This is one good reason to think twice before paying large sums for packaged plant as offered by some Middle European players.

[biofuels-biz] Re: drying oil
A question of rheology. Much recent talk of using centrifuges, spray dryers etc. to remove water from oil. If the oil, water and other minor constituents were Newtonian fluids of differing density at room temperature, there would be no need for any of this. Simple gravity settlement would eventually stratify them for easy separation. Heating seems to help, which suggests that some of the minor constituents fuse (melt) at temperatures between 20C 80C. But heating alone seems not to be the complete answer. A centrifuge does 2 things: it increases the gravity acceleration many times over; and it vibrates a little (sometimes more than a little). Merely increasing 'g' will not cause separation of fluids which do not separate under normal gravity. The fact that centrifuges DO appear to work must therefore be due to the vibration. This would be logical if the minor constituents are non-Newtonian and exhibit a yield stress characteristic. The vibration would create transient stresses within the mixture of fluids. If the peak stress is greater than the yield stress, then shearing can take place and settlement can progress (quickly in a centrifuge or slowly in a simple tank. My proposition, therefore, is that we should forget centrifuging and stick to gentle heat and vibration. As an aside, Simon (or was it Martin?) has reported that the vibration caused by attaching his air pump to the side of the bubble washing vessel seemed to improve that process.

Terry Biofuels wrote in the other list: No real need to boil after washing - if you want, take it up to 80 deg C and most water will drop out. Murkiness is probably tallow esters, if temperature is below 8 deg C and pH is 7. Warm slightly, when it will disappear. Allow tallows to settle for a week - draw off from top and use 100% - mix the lower murky layer with warm petrodiesel to achieve cold weather properties. This is not sacrilege - any petrodiesel replaced is good petrodiesel! which exemplifies a question which will arise in small-scale commercial production. As in any process, a certain amount of product will be off-spec and therefore unsaleable. Nevertheless, such 'seconds' may be perfectly useable in-house by operators vehicles. It is therefore worth keeping records of the quantity of off-spec likely to be produced so it can be compared with anticipated in-house consumption. Any comments?

Re: [biofuel] Engine oil and ADDITIVES
Quote from a MAFF report: 12 1.0.iii Oil Crops - Markets The total world production of vegetable oils is over 85 million tonnes, with more than 80% originating from soya bean, oil palm, rapeseed, sunflower and coconut. Whilst the majority of this oil is used in the food industry 25% is used in non-food or technical applications, by the oleochemical industry. Oil Crop market areas Lubricants It is reported that around 740,000 tonnes of lubricants are used in the UK each year, whilst the EU market for lubricants is reputed to be some 4.5 million tonnes (59). Of these, over 580,000 tonnes (13%) are unaccounted for after use and presumably lost to the environment. The loss of hydraulic oils is believed to be around 8% whilst for engine oils the figure proposed is 34%. Further to this the European Environmental Agency has estimated that around 260,000 tonnes of oil are lost in the North Sea each year (59). It therefore seems logical that vegetable oil-based lubricants are perceived to have the greatest competitive advantage in total loss systems e.g. chain bar oils, two stroke marine engines, drilling muds, agricultural greases and possibly in applications where the risk of loss is high. e.g. certain hydraulic systems. In such cases their negative impact on the environment is much less than that of mineral oil-based lubricants. Although they are more expensive than mineral oil-based lubricants, less is needed per tonne of wood cut, so the cost is no greater. However, their extensive use in these contexts is likely to be dependent on specific environmental legislation (as is the case in Germany and Switzerland). Nevertheless, since April 1995 the UK's Forestry Enterprise (a division of the Forestry Commission) has adopted a policy of using environmentally-friendly lubricants to lubricate chainbars and chains, in both their motor manual systems and automated harvesters. The UK's Environment Agency is also keen to promote the use of more environmentally-friendly products. At the 'Lubricants from oilseeds workshop' held in London on 9th May 1996, Dr Harold of Lubrizol International Laboratories stated that the estimated potential EU market for biodegradable lubricants was in the region of 370,000 million tonnes (10). However, to date only a fraction of the market (35,000 tonnes) is actually derived from vegetable oils (see also Table 1.4).

Ignition is by exothermic catalytic heating of methanol on hot platinum alloy coil (glow plug), in addition to compression heating. To take advantage of biod's great lubricity plus ability to burn, I tried a straight mix of biod + methanol. Of course they do not mix, so this approach is NBG. (This must also be the reason most of the XS meth ends up in glycerol rather than in the biod.) Model diesel fuel (conventional) is 30% ether, 20% oil, 50% paraffin. I tried a few alternative mixes and found 75% biod, 25% ether worked OK. Note the complete omission of separate lubricant. No sign of overheating or siezing even with prolonged running on several different engines (I have quite a collection, including some of the excellent Irvine diesels which are no longer made, just glow motors now).

Here's a repeat of an earlier post which had no response at the time - Original Message - From: David Teal [EMAIL PROTECTED] To: biofuel@egroups.com Sent: Monday, January 22, 2001 1:31 PM Subject: [biofuel] Dale's machine Yes, Dale's biodiesel processor setup as described on his website looks very useful. http://home.swbell.net/scrof/Biod_Proc.html One aspect might be more than a little daunting for backyard experimenters though. Not everyone has friends with a spare vacuum pump, so I should like to share an idea I am working on for just this purpose. Any model aircraft engine (2 stroke or 4 stroke) can be made to work as a vacuum pump. All you need to do is: *Remove the glowplug to reduce heat generation by adiabatic compression *Spin the engine with an electric motor *Connect the vacuum tube to the air intake *Connect an oil supply to the needle valve (biodiesel is good lube) This setup certainly works, but I haven't tested it to the 25hg mentioned by Dale.

Re: [biofuel] Vapour Carburetion
Another way anybody can estimate the power needed to keep their vehicle moving at constant speed (air resistance + rolling resistance) is to coast in neutral down a long hill. Note the terminal speed reached, the weight of the vehicle, and check on a contour map to find the gradient of the downhill road. I have done this, and found: *The same vehicle will be faster when heavily loaded (makes sense) *Different vehicles of similar weight reach different terminal speeds (aerodynamics) *15 hp for 60 mph quoted by David Reid is a reasonable figure Power = force * distance/time force = weight of vehicle * sine of road gradient distance/time = speed Not too hard if your units are consistent. I have been slightly amused by the Vapour Carb dialogue, exemplifying the process by which men eventually solve paradoxes. Carnot is the limit for any heat engine.

Hi Munir, I know Malaysia quite well, used to visit Ulu Perak every year (tin mining small hydro) and Sabah a couple of times. It may be that during your humid monsoon seasons there may be not much benefit from the fogger, but the hot dry season could be a different story. Anyway, it will be good to get your feedback. David Teal hi david dick.. i just fitted a fogger using dick's system few hours ago. it is the simplest of all fogger i've come accross. thank's dick:)..i'm using a honda integra 80's model using carburetor. i kept it as a secret to my friends. but hey, they notice that my engine run quiter. well david, at least rather than nothing. i'm staying in malaysia (tropical climate). in a few day, i'll get result on how much gas saving the fogger can give me. regard's.. munir..

Re: [biofuel] Re: small diesels and filtering fat
Kevin, There is not likely to be any water in 350 F oil. If you can insulate your barrels, then you would not need to re-heat before starting with the acid (or other) transesterification. No need to filter at this stage, you can do it later, either between transesterification stages or at the end. Everthing will cool down during washing, but you should filter again after drying.

Re: [biofuel] more windpower
robert luis rabello wrote I found the site. Please check out the following link: http://www.wvt.de/englisch/index.htm They claim the start up speed with NO LOAD is .3 meters / second. I looked at the power curve on the site and it didn't seem like they were making any outrageous claims for low wind speed performance. The genny is a peculiar looking thing, however! I had a look at this. It has indeed a strange blade configuration, which possibly explains why the performance graph is unlike any conventional wind turbine. Instead of power increasing with the cube of windspeed, the relationship is not much better than linear. I would guess that at tip speed ratios away from optimum there is excessive drag, which severely restricts output torque at higher windspeeds, and is probably noisy despite the designer's denial. Despite the above criticism, I actually quite like the design, as it seems to use centrifugal force to maintain blade shape a bit like a Darrius, and the drag feature is good safety for storm survival. In other words, not efficient, but a different way to a practical result.

Re: [biofuel] BD glycerol validation
Still banging on about quality control: If the Aladdin test is NBG, then how about making a micro-batch from supposedly finished biod (reacted, washed dried). Possibly use the methoxide mixer as a reactor vessel, otherwise an insulated 1.5 litre coke bottle if you don't mind getting some arm exercise. Use some left-over methoxide with the heated biod feedstock. The possible results would be: *Nothing visible:OK *Soap formation: biod was not quite dry *Glycerol drop-out: oil was not fully reacted The micro-batch would be high in methanol, but can be added to the next main batch.

Re: [biofuel] BD glycerol validation
Micheal has a very good point here, and I have had a few thoughts on a practical measure for residual glycerol. My suggestion makes use of the fact (true??) that glycerol does not burn at 200 to 500 deg.C, but esters do. The test, then, is to put a known mass of biodiesel into a simple oil lamp burner, with a wick. Then light the lamp and allow it to burn down to a lower known mass. Any glycerol content of the biod which has burned will have accumulated in the wick. The Aladdin test, then, is to weigh the wick before and after the burn and so get a measure of glyc content. Obviously, some refinements will be needed, but I reckon the basic principle is OK for home laboratory use. Try it before and after washing y'all. Any other ideas?

[biofuel] Fraud alert
DIESEL FUEL FRAUD UNCOVERED Millions of litres of low-quality fuel has been sold as diesel in a sophisticated fraud, reports say. Up to 50m litres of lubrication oil has been laundered in an industrial-scale operation in the north of England and sold cheaply to petrol stations. Customs officers are now preparing prosecution orders amid fears the trade is linked to terrorism in Ireland.

Re: [biofuel] Spirit hydromter in UK
Standard wine-making hydrometer measures from 1.150 to 0.970 sg. This is no good if you want to measure 0.85 sg spirits. However, you can fashion a float from closed cell blue foam or similar to place under the hydrometer. Sand it down until it reads 1.150 when immersed in water. This gives an offset of 0.15, so the range becomes 1.000 to 0.820 sg QED. David Teal Yahoo! Groups Sponsor -~-~ Make good on the promise you made at graduation to keep in touch.

Re: [biofuel] Help for setting up fuel cell energy source for small village.

[biofuel] Blue stone blues
There has been talk about disintegration of the blue aquarium stones used for bubble washing. This is unfortunately true, but there is a quick and cheap remedy. Discard the stone and its soluble plastic connector. Empty the contents of a tea bag through a small hole. Push the air tube into the hole in the tea bag and wire it up tight. Wind a lead weight round the tube nearby to make sure it sinks. Fire up the pump and there you have it. QED David T Yahoo!

Re: [biofuel] Re: criminals, brown's bomb, hydrogen fusion, and ph measurements ...(#339)
I did make a mister (Novak's baby) for my 2,8 litre Vauxhall Royale petrol car. It probably works too well and consumes a litre of water/ethanol mix in a few miles. It also makes the engine race in neutral, so I put a valve in the suction line to reduce the flow rate. I don't use this thirsty vehicle enough to have come to any conclusion as to its effect on performance or economy.yet. Provisionally, I subscribe to the theory of better combustion of the complex hydrocarbons, possibly with a catalytic reaction in there somewhere.

Re: [biofuel] Re: Gum?, wax?, soap?, glycerol?
Alecs asked: First which Two step method? Base-base or acid-base? You got alakline glyc there. Glyc is not solid at room temp, but with all this lye floating arroun, it's gel like. The base- base two stage glyc burned, because it was fluid. It was fluid because of lots of methanol in it. Once lighted it burns with a strong, hot, yellow flame (sodium ions). After burning it leaves a black gum residue, which has to be removed from the burner. The same happens to the injector tips of your engine if you use not thoroughly cracked bio (min 95% crack). I had 3 answers to my question, suggesting gelatin, glycerin and alkaline glyc. (Alecs, the base-base method was used). As the solution is strongly alkaline, I think the last one is probably it. Todd noted that excess methanol was burning in my crucible, and this brings us round to easy ways to recover this costly ingredient. I was impressed by Dale Scroggins' vacuum distillation method, and wonder whether anyone else has experience of this. Can it be done just on the residue after decanting off the oil (much smaller volume to handle)? David Teal Yahoo! Groups Sponsor -~-~ Make good on the promise you made at graduation to keep in touch.

Re: [biofuel] Methanol Help
Hi David I keep hearing of this. Do you have some good references? TIA Keith Addison From http://jin.jcic.or.jp/trends98/honbun/ntj980623.html. (as Keith lives in Japan :-) The worldwide total of methane hydrate is estimated to be equivalent to 250 trillion cubic meters of methane gas. Research on this substance has been active overseas since the early 1990s, but attention is focused more on its potential to contribute to climate change than to provide energy. If temperatures were to rise on a global scale, causing some permafrost to melt, then massive amounts of methane would be released into the atmosphere to aggravate global warming. This would create a relentless cycle by melting yet more permafrost, thereby releasing even greater amounts of methane. From http://marine.usgs.gov/fact-sheets/gas-hydrates/title.html The worldwide amounts of carbon bound in gas hydrates is conservatively estimated to total twice the amount of carbon to be found in all known fossil fuels on Earth. From http://www.unsolvedmysteries.com/usm36060.html Our enviroment is in deep trouble these days. Emmissions from burning fossil fuels from coal, oil, and gas have polluted our atmosphre. Higher than normal amounts of the greenhouse gas Carbon Dioxide has been suspected to be causing global warming. But is it really worse than that? Maybe carbon dioxide should be our least concern. Locked inside of the oceanic crust of the Earth, there are deposites of a substance known as Methane Hydrate. While it's usually frozen in the underwater depths, some of it in gasous form can escape from the ocean floor and come near the surface. It's been known to sink ships, since it can lower the boyancy of the water, and the ship is unable to float. But to make matters worse, methane hydrate is also a greenhouse gas, and it's unknown exactly how much of it there is underwater. Scientists say that while carbon Dioxide can raise the global tempiture up to 5 degrees F in the next 100 years at it's present rate of increase, Methane Hydrate can raise it 13 degrees in only 10 years. The climate could be ruined, crops will fail, storms will get worse, and in less time than anything humans can do. And while we can control CO2 Emmissions, Methane Hydrate is nautral, and unstoppable, should it happen. However, Methane Hydrate can be used to do good. It is a combustible substance, both in solid and gas forms. And it burns much cleaner than fossil fuels can. While we don't have the technology to begin extracting large amounts of it, maybe in the future, it can be an alternative energy source. Carbon Dioxide will be reduced, and the harmful Methane Hydrate would be used up, so it couldn't cause much damage to the world. The atmosphere could become a much cleaner place. - Original Message - From: Keith Addison [EMAIL PROTECTED] To: biofuel@yahoogroups.com Sent: Thursday, March 01, 2001 6:54 PM Subject: Re: [biofuel] Methanol Help Terry mentioned methane hydrate, the solid stuff.
