[biofuels-biz] glycerine bi-product
David, just to re-cap - we are talking about the dark, oily layer that floats to the surface of the glycerine bi-product. Again, I don't know what this stuff is and I'm not convinced it is FFA. The only sensible answer I can think of is that it could be a result of scission of unsaturated fatty acids and repolymerisation to form diesters, like synthetic motor oil? Nobody has yet produced any proper scientific evidence that this top layer is FFA, none that I know of anyway. If anybody out there has got anything concrete, then let's have it! In the mean time, Keith, if you're tired of the topic I suggest that either you don't read it or we move it to another list. No offence is meant here. You have produced a great amount of excellent information Paddy 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. Personnally, I don't have any other explanations, although I'm sure there are others more qualified to comment Paddy Biofuels at Journey to Forever http://journeytoforever.org/biofuel.html Biofuel at WebConX http://webconx.green-trust.org/2000/biofuel/biofuel.htm List messages are archived at the Info-Archive at NNYTech: http://archive.nnytech.net/ To unsubscribe from this group, send an email to: [EMAIL PROTECTED] Your use of Yahoo!

[biofuels-biz] butanol process
I've just been told that it works well.

[biofuels-biz] butanol process
Dear all, I've been talking to a chemist who used to in the paints industry and he has suggested a process for esterification of FFA's that removes the water produced as it goes along. Apparently, it seems to be based on the fact that butanol has a similar boiling point to water and will also seperate out when cold, so the miture can be condensed into a seperatory funnel which has a take off side arm that feeds butanol back into the mixing vessel and a bottom tap to remove the water. I am informed in very good faith that this works well ... Paddy. ps Happy new year!

[biofuels-biz] skin on biodiesel
If there are any drying oils present in the oil (such as linseed, fish or flax-oil), oxidation of the relevant unsaturated fatty acids can be expected to form a polymeric film on the biodiesel/air interface. It reforms every time the surface is broken until it is all reacted with the air. I wonder if that could be an alternative explanation? Michael Allen have noticed that raw biodiesel from tallow readily forms a skin as it cools, but the same BD after washing does not. Paul Gobert. ... yes drying oils sound like a possible explanation and Paul's contribution kind of kicks my suggestion out of touch! This could be confirmed by picking up a bit of the skin with a spatula a checking for solubility in water Paddy Biofuels at Journey to Forever http://journeytoforever.org/biofuel.html Biofuel at WebConX http://webconx.green-trust.org/2000/biofuel/biofuel.htm List messages are archived at the Info-Archive at NNYTech: http://archive.nnytech.net/ To unsubscribe from this group, send an email to: [EMAIL PROTECTED] Your use of Yahoo!

[biofuels-biz] Canakci/Van Gerpen
What do you think the interest would be if you were able to remove (most/all) water from WVO at low temperatures (no need to waste a lot of energy boiling). Canakci/Van Gerpen were only looking at a very small stage of the biodiesel making process - the esterification of FFa's - which is a highly desirable thing to do, especially if we wanted to use something like palm oil. when performing this reaction you can see the water forming as the onset of cloudiness. It seems to me that this could be avoided with suitable reagents that would absorb the water as the reaction was taking place, making the process worth the effort. Otherwise, the FFA's can be removed as Kieth suggested, by adding alkaline fluid. Personnally, I don't think that water can be removed from WVO without a fair bit of heat, but no doubt someone on the list more informed than me would like to have something to say here. I'm certainly not a guru on the biodiesel subject, just a small scale operator trying to get a good process going ... Paddy Yahoo!

OK Keith, re: Why do you think the three layers are not what Todd and I say they are, and what do you think they are?

I'll try and test the top layer and let you know what the results are. I won't, however, be able to do this for a while as I'm pretty busy with other things which have higher priorities, which is why I asked if anybody had done it already as it would save me the bother.

[biofuels-biz] neuralised layers in crude glycerine and high FFA feedstocks
I don't necessarily disagree with Todd's thoughts as to the constitiution
of the 3 layers, I was more interested in why he thought what he did rather
than what he thought (all due respect to Todd). It should be easy to test
what the top layer is by performing an acid esterifcation with methanol and
confirm that it is free fatty acid - has anyone done this yet? Also, whilst
on the subject of FFA's, with the feedstock that I have been using the
'foolproof' method does not yield glycerine that can be collected. Common
sense says to me that if you don't remove the product of the reaction it
will simply go into reverse when the base catalyst is used. Excess
methanol could be used to make the glycerine float in the methanol layer and
this would take the water with it, which could then be removed. The
literature I have read recently
suggests a 2 stage acid reation with excess methanol, removing the methanol
layer at the top each time. ('biodiesel production from oils and fats with
high free fatty acids, Canacki and Gerpen 2001'). My own conclusions about
FFA's are:
1. They are probably soluble with glycerol and water
2. They have higher melting points than their related methyl esters in the
order of 30 degrees C.
3. To produce high quality biodiesel that won't coke engines they should be
esterified with acid and methanol. Please discuss!
I would be happy to scan the paper mentioned above and send it to
individuals interested, although it is copyrighted and should not be put on
the 'net without permission - anybody want a copy? Paddy

[biofuel] reports on the use of SVO
There are dozens of reports on the useage of SVO compared to biodiesel and fossil diesel. Some also mention blends as well. Many contradict each other and most of them use standard test regimes that try to simulate typical engine useage, such as frequent starting and stopping with a cold engine. To get meaningful results the scientists would need to change their test regimes to accomodate switching fuels from, for example, fossil diesel to SVO, and nobody seems to be prepared to do this as most advocate the use of methyl or ethyl ester biodiesel. Further tests on SVO seem unlikely as the scientific community is now hard set on biodiesel as their preferred veg oil fuel. However, SVO users will learn by our own road transport use which vehicles are the best suited and which one's are no good - it will take time to clock up the high milages necessary to get proof - maybe ten or twenty years of continual use.

wrt catalytic converters ... this is all i could find: Article Title Effects of an Oxidation Catalytic Converter and a Biodiesel Fuel on the Chemical, Mutagenic, and Particle Size Characteristics of Emissions from a Diesel Engine Authors Bagley, S. T. Gratz, L. D. Johnson, J. H. McDonald, J. F. Serial Title ENVIRONMENTAL SCIENCE AND TECHNOLOGY -WASHINGTON DC- Abstract This study was conducted to obtain additional information on exhaust emissions with potential health importance from an indirect injection diesel engine, typical of those in use in underground mines, when operated using a soy-derived, fatty-acid mono-ester (or biodiesel) fuel and an oxidation catalytic converter (OCC). Compared to emissions with the diesel fuel without the OCC, use of the diesel (D2) and biodiesel fuel with the OCC had similar reductions (50-80%) in total particulate matter (TPM). The solid portion of the TPM was lowered with the biodiesel fuel. Particle-associated polynuclear aromatic hydrocarbon and 1-nitropyrene emissions were lower with use of the biodiesel fuel as compared to the D2 fuel, with or without the OCC. Vapor-phase PAH emissions were reduced (up to 90%) when the OCC was used with either fuel. Use of the OCC resulted in over 50% reductions in both particle and vapor-phase-associated mutagenic activity with both fuels. No vapor-phase-associated mutagenic activity was detected with the biodiesel fuel; only very low levels were detected with the D2 fuel and the OCC. Use of the OCC caused a moderate shift in the particle size/volume distribution of the accumulation mode particles to smaller particles for the diesel fuel and a reduction of particle volume concentrations at some of the tested conditions for both fuels. The nuclei mode did not contribute significantly to total particle volume concentrations within the measured particle size range (asymptotically equal to 0.01-1.0 ¾m). The biodiesel fuel reduced total particle volume concentrations. Overall, use of this OCC for the engine conditions tested with the biodiesel fuel, in particular, resulted in generally similar or greater reductions in emissions than for use of the D2 fuel. Use of the biodiesel fuel should not increase any of the potentially toxic, health-related emissions that were monitored as part of this study. Yahoo!

I evaporated a load of such water and it reduced to a very small amount of an oily substance which could be anything, but probably digestable by micro-organisms ... might be worth testing this on a small scale.

[biofuel] glycerin use
I reply to: I am a member of this group since 2000, but I had no quastion until now. I have a big problem what to do with glycerin. I am pripare to buy a expensive (cca.60.000,00 $) vakum destilater to puryfai (clean) glycerin, but do not now for what use is than that glycerin. I make glycerin from waste wegetable oil. Please help me! Thanks egon As with a lot of info on the net, there seems to be a lot of contradictions. Glycerin has been said to be a valuable biproduct, but retails at £750.00 per tonne (GBP) ex Albion chemicals, UK, which is not that fantastic for the producer. Other possibilities discussed have been for fertiliser (not a good option for myself) or as a furnace fuel for heating oil for drying or getting to reaction temperature. Nobody seems to have come forward with a good design for the furnace, which would involve preheating the fuel to about 500 degrees C to get a clean burn, but I peronnally think this is the best option and intend to persue this avenue. My stock pile of glycerine are beginning to become a problem and i don't want to dump it as waste. [Non-text portions of this message have been removed] Yahoo!

[biofuel] UK environment agency
Kieth, thanks for your encouragement and comments on possible biodisel pollution. I have it on good authority that the UK environment agency require a 'bribe' of approx $USD 30,000 to analyse possible pollution. If biodiesel plant dischaeges mirky water into the water system here without authority big fines are payable, whether it's biodegradable or not. The UK is a very polluted place and, being a small island, nowhere is far from the coast. Personally I don't blame the authorities for taking a tough stance. If a biodiesel factory was discharging mirky water on my favorite beach I would not be happy, being a keen windsurfer. There's already a huge sewerage problem all round the coast and most rivers are already full of all kinds of crap. Yahoo! Groups Sponsor -~-- Tiny Wireless Camera under $80! Order Now!

[biofuel] Solid catalyst,
Yes, Dana, there are people interested in finding greener recipes for making biodiesel. They do seem to exist but are generally highly guarded industrial secrets. I got a bit disallusioned by the polluting effect of the basic methanol/lye method as it produces a lot of mirky water in the refining process which is a problem to serious biodiesel producers as the local environment agency (UK) is highly officious and very fond of imposing large fines on businesses that cause pollution. I am currently researching other methods. Yahoo! Groups Sponsor -~-- Tiny Wireless Camera under $80! Order Now! FREE VCR Commander!

[biofuels-biz] enzymes
A lot of the research on enzymes that has been done is available through journals and conference notes published. It seems to be tricky to get hold of this information although apparently the british library in London has many of the relevent papers. The website http://www.delphion.com has details of various american patents which can be viewed for $3.00 each. One thing that I did find out after only a small amount of research is that glycerol can be turned into glycerol ethers with very little effort, which can then be added to the methyl esters with beneficial results. I realise that these topics are a little bit off subject and maybe better discussed on the biofuels discusion group, but there's bound to be some overlap. A useful patent to read is patent no. 5,713,975 (Foglia et al) which claims for a method using different enzymes that is ' particularly advantageous because it utilizes inexpensive feedstocks such as animal fats, vegetable oils, rendered fats and restaurant greases as substrates.' The methods still use alcohols, but are not limited to methanol. I hav'nt found anything that does'nt use any alcohol yet. With reference to business issues, the enzymes are expensive, the process seems to be more tricky, there may be more equipment needed, more time for the reaction but they deal with free fatty acids more effectively. Who knows? This is all conjecture at this stage!

[biofuels-biz] enzymes
Harry! Glad to see there's some interest in this method of 'biodiesel' production. I think you're right that it would no longer be called biodiesel, there's a company called Ebony solutions in Chester, UK that produces what it calls 'E-diesel'. They claim improvements in performance over fossil diesel and I am informed that there are no bi-products. I think that your ideas about the possible use of micro-organisms or lipase enzymes are on the right track, I'm trying to remember my biology from school and have vague recollections of enzymes helping to break down fats in acidic conditions in the stomach. I will try to speak to somebody with better knowledge on the subject. Cheers for now ... Paddy I note that the Coco diesel doesn't claim to be methyl esters. Digestion by micro-organisms is an obvious step in Oil extraction if the product doesn't need to be edible. It is quite likely that some yeast like bugs would target the glycerol part of an oil molecule, releasing FFAs. In fact any bug that causes rancidity would be expected to do just that. Many of the countries that produce excess coconut require stationary desiels that can easily be converted to SVO and coconut has the advantage of requiring next to no refining compared to other vegy oils that contain gums etc.. Hanns has worked for some time on practical alternatives for direct oil extraction from fresh coconuts-When he returns fron New Guinea I will refer this thread.

[biofuels-biz] small production plant
There's nothing revolutionary about this trailer plant. It was an idea concocted with help from John Nicholson and of bio-power and the design overcomes a lot of potential problems associated with oil spillage, health and safety, planning and business rates. The bio-diesel part of it is very conventional .. mixers, settlement tanks, centrifuge etc. and there is no automation like Dick Carlstien's plant at present. Also, it should be made clear that the bio-diesel equipment is not yet complete and the plant as a whole will not be available untill April 2002. There are photographs of some of the prototype mixers and settlement tanks at the following address: http://www.goatindustries.fsnet.co.uk/alternativeroadfuels/alternativeroadfu els.htm The trailer is being worked on as we speak and the basic layout can be made available to the group if there is continued interest ..

[biofuels-biz] 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. Hmmm does anyone really know the answer? David Teal I certainly hav'nt got any solid answers to the vibration technique talked about but my own observations support everything you have just said [Non-text portions of this message have been removed] Yahoo!

[biofuels-biz] what's going on?
I've been following these conversations about acid base reactions etc. Excuse me for perhaps being a bit thick, but what advantage does adding acid have? Also I'm mystified why tolerate 3 hours mixing times ... we mix heavily used wvo in 15 mins with excellent splits ... recipes are made to be broken are they not? ... Paddy - Original Message - From: [EMAIL PROTECTED] To: biofuels-biz@yahoogroups.com Sent: Monday, July 02, 2001 5:08 PM Subject: [biofuels-biz] Re: Bio- vs. Palm Oil? This is getting tedious, I'm simply reporting what I found. I followed the acid base recipe and got a low calorific value fuel. After the acid was neutralised and allowed to settle, I ran the 1.5g of NaOH as per the recipe. This did not transesterify all of the oil. I therefore repeated the base reaction with more methoxide at 1.5g of NaOH per litre of oil. The changes I had to make showed that my oil has less FFA to be reacted by the acid than Alecs would normally have. He agreed that this would happen with lower FFA oils. A titration would have shown that, but I was following the recipe and experience told me that it had not completed. As I used a large excess of methanol I washed the product with 4 water changes. Wasteful, but I did not want the methanol reducing my fuel's CV. My result was a low Calorific Value fuel. Why? Idea 1 Acid burnt oil? Maybe, but would that reduce the CV? I would expect any unreacted glycerol to hold up the energy value. Idea 2 Some oxygens were lost - they help to maintain the miles per litre if not the measured Calorific Value. Idea 3 Maybe the FFA was stripped of any remaining glycerols, but not turned into methyl ester. Clean FFA has a lower CV than methyl ester. BTW Martin was told by Tegasc that acid/base reacted biodiesel is not as good as purely base reacted biodiesel, but the details were not quantified. We need some proper research on this - not simply me messing about with home-brew. Somebody else please try the acid/base recipe with heavily used oil and then do some miles per gallon comparisons with purely base reacted ester. Hopefully both will be the same, but I'm sceptical. Dave --- In [EMAIL PROTECTED], Keith Addison [EMAIL PROTECTED] wrote: Hi Dave Hi Keith, Alecs does qualify that in his recipe's. He means that the process reaches an equilbrium before all of the oil is converted. He says: Esterification is followed by transesterification, but under acid conditions it's much slower than under caustic conditions and it won't do a complete oil-to-methyl ester conversion as the reaction is much more equilibrium-sensitive. Without methanol recovery, the alcohol overdose required would make the price of your fuel jump, and even with recovery it would still be much more expensive. Hence the second base-stage. That doesn't mean the process reaches an equilibrium before all of the oil is converted, it means what it says: the first stage won't do a complete conversion, hence the second stage. In theory you can never get to 100% conversion to ester etc. He also hates to not convert the FFA to ester. While I agree it's wasteful to dump the FFA, I'm not convinced FFA can make DIN 51606 standard ester. Clean FFA can be used in blends for low speed site plant or heavy oil generator engines. That said, Energea use an acid pre-reaction for 8% FFA feedstock and they deliver DIN standard fuel, so it can be done. I'd like to compare calorific values (per litre) of ester from high FFA feedstock and new oil. Methinks Teagasc also do it. There are quite a lot of people making it and using it in their cars and reporting no problems; some report improvements, smoother running. It checks out as high-quality. Simple comparative tests find it's the equal of commercially produced biod from Austria. Why relegate it to low-speed gear and generators? What are your doubts based on, exactly? Anything concrete? A single stage (base) reaction with new oil might make biodiesel which is less than 2.5% oil, but 10% unreacted oil is more likely especially with RVO. Reacting in 2 stages gives a good chance that the ester is more or less fully converted. You react with 2/3 of your methoxide and allow it to settle. Then draw off the byproducts and react again with the remaining methoxide. This polishes the ester. Shorthand is base/base process. So, to answer my question, your normal base-base process is Aleks's two-stage process. He'd certainly be surprised that this is what gave you sloppy biodiesel, the usual result is high quality. I think Energea plants do three reactions to make absolutely sure they are within the standard. Unused methanol is recovered so there's no waste. Some plants do more than three reactions. When I followed Aleks Kak's Foolproof Process my waste oil was not as overcooked as he uses so I needed to do

VW have said that they stock conversion kits allowing most post 1995 vehicles to use 100% RME. Before that they won't commit themselves. Most vehicles are Ok with a 20% blend ebven though manufacturers warranty are often an issue. For the time being, our market is out of warranty commercial vehicles.

It had new fuel lines with a cheap filter ahead of the main fuel filter to catch the tank rubbish. The tank filler tube and gaskets are original, but probably well past their best. The fuel pump was rebuilt last year but corrosion damage was due to wet fuel not biodiesel seals were OK. 5 Injectors replaced 15,000 miles ago, but one refused to move. Recent attempts sheared it off. Problem was corrosion between injector body and cyl head - not biodiesel related. When stripped engine was remarkably clean apart from (as expected) the cyl with faulty injector. Even that was not as bad as the injector condition would suggest.

Re: [biofuels-biz] which vehicles can run unmodified on biodiesel?
to quote an excerpt from the national biodiesel's board ... Compatibility of biodiesel with engine components. In general, biodiesel will soften and degrade certain types of elastomers and natural rubber compounds over time. Using high percent blends can impact fuel system components (primarily fuel hoses and fuel pump seals), that contain elastomer compounds incompatible with biodiesel. Manufacturers recommend that natural or butyl rubbers not be allowed to come in contact with pure biodiesel. Biodiesel will lead to degradation of these materials over time, although the effect is lessened with biodiesel blends. If a fuel system does contain these materials and user's wish to fuel with pure biodiesel, replacement with compatible elastomers is recommended. The recent switch to low sulfur diesel fuel has caused many OEMs to switch to components suitable for use with biodiesel, but users should contact their OEM for specific information.
