Re: [biofuels-biz] Fwd: Biorefinery projects take first steps
Hello David 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? They certainly are, we, hopefully, are not. Feedstock and product both. I don't think replacing Big Oil with Big Biofuels would necessarily be much of an improvement, if any, and maybe even worse. It'd be many or all of the same players, with all the same precepts that we've come to know and love, along with Jolly Nice Folks like Archer Daniels Midland, Dow-Cargill, Monsanto, et al. But at least there'd be less greenhouse gas emissions? Maybe not even that - very large amounts of land would be turned over to intensive agribusiness monocropping of biofuels crops, with huge fossil-fuels inputs (and the usual massive externalizations). As it is, agribusiness is a very major producer of CO2. (So they'd help use up the remaining oil even faster.) At least the petroleum resources are underground and don't take up that much surface area, but this stuff would blight the land. Of course their thinking and planning would be to provide enough biofuels - enough to replace dino-d use with growth calculated at current rates, so business-as-usual as far as highly inequitable and unsustainable OECD energy use is concerned. That's just how the US DOE does calculate it. Quote from a speech by a biodiesel industry figure (Tim Haig): ... in the year 2001, the European Union produced and used 300 million gallons of biodiesel. In the United States last year [2001], they produced and used 35 million gallons. The projections are as follows: by the year 2016, the US expects to produce in excess of 800 million gallons. The Department of Energy has gone on the record to say they are in support of six billion gallons by the year 2020. That would be 15.5% of the diesel consumed in North America, and that is indeed possible to do. This won't get us very far, it certainly won't get us a sustainable energy future. That, as I often say here and at the Biofuel list, and so do quite a few others, means greatly reduced fuel use, greatly increased fuel efficiency, and, most important, decentralization of supply. That's not what we're going to be getting from the USDA or the US DOE or their ilk. 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. That is interesting. But many other catalysts can be used apart from sodium methoxide. Would they all form such a complex? regards Keith Yahoo! Groups Sponsor -~-- Buy Ink Cartridges or Refill Kits for your HP, Epson, Canon or Lexmark Printer at MyInks.com.

Re: [biofuel] RE: daihatsu - was Digest Number 1832
Hi Dan Keith Addison said: Also the wvo that i have acquired is mainly ground nut oil rather than rape. It shouldn't be a problem. It's not a drying oil, so it won't polymerise. I'm probably wrong, but you may wish to double check and make sure that the nut oil you are getting is not a drying oil. In the work I've done, finishing wood, nut oils are usually drying to one degree or another. As this experience is from wood working and not biofuels, it may not apply. Make sure the oil you are getting isn't a drying oil. Indeed. But groundnuts/peanuts aren't really nuts, nor do they come from trees. It's an annual legume, in other words a vegetable, and the nuts are a sort of underground bean. Peanut oil has a lower Iodine Value than rapeseed oil, and it's quite a lot lower than soybean oil. Peanut oil - 93, Rapeseed oil - 98, Soybean oil - 130, Tung oil (drying) - 168, Linseed oil (drying) - 178, Sardine oil (drying) - 185. Best Keith Dan Yahoo!

Re: [biofuel] glycerin use
No. First, you would need to find to incorporate an emuslifying agent to get the glycerol to mix with the oil. Second, you would also be adding a water fraction unless you distilled it out first. (The presumption is being made that you are speaking of glycerol/ffa separation as discussed at http://journeytoforever.org/biodiesel_glycsep.html ) Third, you would be increasing the ratio of glycerol to fatty acids by adding it to the already-glycerol-bearing glycerides (SVO). Aside from that, one has to ask why would a person extract glycerol from glycerides (make biodiesel) and then add a fluid that is as thick as molasses back to a fluid that is already as viscous a fluid as SVO or WVO?

[biofuel] Producing cellulosic ethanol
An article below QA with Iogen... but first something -- ABOUT The Environmental and Energy Study Institute (EESI) is a non-profit organization dedicated to promoting environmentally sustainable societies EESI was founded in 1984 by a bipartisan group of Members of Congress concerned about energy and environmental issues. http://www.eesi.org/about/about.htm - ECO Newsletter - Published monthly, this newsletter provides an open forum for discussion of Ethanol, Climate change, and Oil reduction issues. http://www.eesi.org APRIL 2003 Q A with Iogenâs Jeff Passmore regarding cellulosic ethanol http://www.eesi.org/publications/Newsletters/ECO/eco%2019.htm ECO recently interviewed Jeff Passmore, Executive Vice President of Iogen Corporation. Iogen [http://www.iogen.ca] is a privately owned Canadian business that has recently announced that its demonstration facility in Ottawa, Canada is successfully processing 30 tons of wheat straw per week into fermentable sugar and is on track to reach annual production of 320,000 liters (roughly 85,000 gallons) of cellulosic ethanol. Potential feedstocks for producing cellulosic ethanol include a broad range of agricultural residues and forest wastes such as sugar cane bagasse, rice hulls and forest thinnings, municipal wastes such as waste paper, yard waste, construction debris, and industrial wastes such as pulp/paper and sludge. According to research done at the Argonne National Laboratory, cellulosic ethanol also greatly reduces the emission of greenhouse gases when compared to gasoline. [SEE: Briefing Summary - Elements of a BioBased Economy: BioBased Energy, Fuels, and Products May 20, 2003 http://www.eesi.org/briefings/2003/EnergyandClimate/5.20.03%20Biomass/5.20.03%20Biomass.htm] Why does Iogen think the development of a cellulose market is important/desirable? Iogenâs goals include meeting the challenge of reducing North Americaâs greenhouse gas emissions, creating a domestic fuel supply, increasing market opportunities for farmers, and creating local jobs. Our technology will allow for major impacts on the CO2 put back into the atmosphere in the transportation sector. The demonstration facility in Ottawa, Canada has been designed and engineered to process up to 40 tons of feedstock per day. Currently, the facility is successfully processing 30 tons of wheat straw per week into fermentable sugar ö which would produce 320,000 liters of ethanol annually. No one has ever used modern enzyme technology to successfully convert cellulose material (a polymer made up of repeating units of glucose, a simple sugar) such as straw into fermentable sugar on this scale before. The demo plant construction began in 1999 and was commissioned in April of 2002. What technology is Iogen using in its demonstration facility? Iogen Corporation is an industrial manufacturer of enzyme products for the pulp and paper, textiles and animal feed industries, and is a developer of technology to make clean fuels from plant fiber. Since it's founding in the early 1970's, Iogen has been focused on the processing of natural fiber, and has made a substantial commitment to technology in the field. The company's effort has resulted in a range of enzyme products used to improve the way fiber is processed. EcoEthanolú is the same as conventional (or grain derived) ethanol; the difference lies in how it is produced. Our focus for feedstocks has been wheat straw and corn stover ö but any cereal straw is useable - as long as the yields make it economical and as long as the cellulose content is there. To be useable in our process, a feedstock must have roughly 60 percent carbohydrate content, and be available in very large quantities such as 750,000 tons per year within an 80-mile radius. There would also be the question of harvesting the material. In laymen's terms what happens is that the feedstock, frequently straw, is crushed into a powder. It is then put through a patented pretreatment process to open up the fibers. Enzymes (a natural catalyst used in many industries) are added to the pretreated feedstock. The enzymes break down the cellulose content into sugar. That sugar is then fermented and distilled into ethanol. In our process we use the lignin in the straw and stover. It can be used to produce electricity and becomes an integral part of the massive greenhouse gas reductions we see with ethanol from cellulose. On average, one dry metric ton of wheat straw will produce 250kg of combustible materials. Of this, approximately 200kg is lignin, all of which can be burned to create electricity. Lignin has around 80 percent of the heat content of typical thermal coal, or approximately 20,000 BTU/kg. Depending on the feedstock used and its growing conditions, there can be a surplus of lignin that
Re: [biofuel] Microturbines vs fuel cells
Greg and April wrote: Possibly, it was what I was told by a friend sometime ago, that was taking a course in school, and one of the problems that they were working on, of course it could of been something else, it was 10 - 15 yrs ago. Noted. As for the aircraft, don't forget that with warm air, it is a lower density and they would need more thrust just to maintain altitude, that in it's self, would cause higher fuel consumption. Ah, yes, Density Altitude. It isn't so much that they need more thrust to maintain altitude, it's really that they need more _throttle_ to maintain altitude. Particularly with piston engines, but also with turbines. This is because the air, which is their working fluid, is less dense, so they become less efficient. In the case of helicopters, when you have less dense air you have to pull more pitch on the rotor blades so you can move a greater volume of the less dense air in order to creat enough lift to hold the thing up. This creates more drag on the rotor system, and results in a higher fuel burn. But the really big worry when operating in hot weather was overtemping the engine. Part of our preflight was to check the density altitude and ambient temperature to make sure we could stay inside the operating envelope of the engine. There was a point at which we couldn't get full rated power out of the engine without exceeding its maximum temperature. It was particularly important to make sure the weather wasn't too hot to _start_ the engine. There were some days we couldn't get it started on batteries, and we'd have to get a GPU start, which was a real PITA. I'm sure this is part of the reason that the OH-58A/C is no longer in the inventory. And even with jets, at high altitude there is a certain throttle setting that you don't go _below_, because if you do then the engines will flame-out. The explanation I got of this was that you needed to maintain a certain compression in the burner section of the engine or it wouldn't have enough oxygen to maintain combustion. The flip side of that is that if you run the throttles too high at high altitudes you risk overtemping the engines. Generally the way pilots fine tune their engines at altitude is to match up the turbine inlet temperatures. Go too high, and the engines literally run out of gas. If I understand it correctly, the service ceiling of the engine is the point at which the maximum throttle setting to avoid overtemping the engine is the same as the minimum throttle setting to avoid flaming out. I could have that wrong, particularly as I'm writing this through an antihistamine/decongestant haze. (Flu sucks) AP Yahoo!

[biofuel] Re: [vegoil-diesel] Chemical jug fitting (long)
Well, leave it to me to reinvent the wheel. I found out what I have built is a dual flow rotating fitting. Now you can buy dual flow rotating fittings, but they're expensive. You can probably get them used from an agricultural junkyard, but I wouldn't bet on it. The good part about doing it yourself is cost. You can either buy something pretty for $150, or build something functional but ugly for around $30. AP Alan Petrillo wrote: Change 1: The 3/8 fuel line has too large an outer diameter to use as a lift tube in the fitting built with 1/2 parts. It causes too much restriction on the return side. I changed the inside hose barb to 5/16, and used 5/16 fuel line instead. This eliminated the restriction on the return side, but we'll see what happens on the supply side. An option would be to rebuild the fitting using 3/4 parts instead of 1/2, but that would make a fitting that's already big and clunky even clunkier. Depending on what happens fuel pressurewise that's what I might have to do. An issue I completely forgot about was venting. Originally I was going to install vents on the jugs, but I changed my mind, and drilled a 1/8 hole in the cap of the tap fitting for venting. Considering the potential problems with polymerization I thought it'd be a better idea to leave the jugs of WVO sealed until it was time to put the tap on them. Alan Petrillo wrote: Here's a fitting I built to enable me to use chemical jugs as fuel tanks. They're only about 5 gallons, but they're easy to get, and cheap or free. Since diesels need both a fuel supply and a return set up as an open loop to function properly, the idea is to build a fitting which will allow this to take place without major modifications to the chemical jugs. This can be built with either galvanized or brass parts, but I chose brass. Whatever you make it from it's going to be ugly, but it'll work. These jugs usually have a 3/4 NPT fitting in the middle of the cap, and that makes building this fitting easy. All of the parts are available at either Home Depot or Lowes. The parts are: One cap from a chemical jug One 3/4 to 1/2 pipe bushing Two 1/2 close pipe nipples (Hex pipe nipples will work, but will make the fitting longer) One 1/2 pipe union (If you can find a proper pipe swivel then use it instead, but if you can find a proper pipe swivel you're doing better than I am. If you do find a proper pipe swivel then please tell me where you got it so that I can go get one.) One 1/2 T One 1/2 male to 1/2 female elbow One 1/2 to 1/4 bushing One 1/2 NPT to 3/8 hose barb One 1/4 NPT to 3/8 hose barb One 1/4 NPT to 5/16 hose barb (Expect this one to be hard to find.) Some 3/8 diesel fuel line Some teflon tape which is approved for petroleum pipe. The tools you will need are a sharp knife, a couple of spanner wrenches and a 1/4 NPT inside tap. A bench vice will help but isn't 100.0% necessary. The fitting is built in two parts. The first is a body that attaches to the cap, and the second is a holder for a tube to pass through the main body. The idea is to draw fuel up through the middle of the fitting while returning fuel through the side. Use teflon tape to seal all of the pipe joints. First, screw the 3/4-1/2 bushing into the cap without using teflon tape, pierce the middle of the cap if it isn't already, and cut it out until the plastic of the cap is even with the inside diameter of the bushing. Then take the cap off of the bushing and put it aside. We'll get back to it later. Screw the 3/4-1/2 onto one of the 1/2 close pipe nipples. Screw the pipe union onto the pipe nipple. Screw the other pipe nipple into the other end of the pipe union. Screw one end of the T onto that pipe nipple. Into the middle of the T screw the 1/2-1/4 bushing. Into the bushing screw the 1/4 NPT - 5/16 hose barb. Using teflon tape this time, screw the jug cap back onto the bottom. This completes the assembly of the main body of the fitting. Now, take the elbow and use the 1/4 NPT inside tap to thread the inside of the male end. Into the now threaded inside of the male end screw the 1/4 NPT - 3/8 hose barb. Into the female end of the elbow screw the 1/2 - 3/8 hose barb. Now take one of the chemical jugs you're going to be using, put the cap with the main fitting on it onto the jug, and then take the diesel fuel line, run it through the middle of the fitting down to the bottom of the jug, and mark the depth on the fuel line. Pull the line back out and cut it off at the mark. Push the fuel line onto the hose barb on the _male_ end of the elbow. Now run the line back through the fitting and screw the elbow onto the top of the main fitting, stopping so that the two outside hose barbs are lined up together.
