Re: [Biofuel] alternative biodiesel process
Hi to all, I was thinking that the most important thing in the business of electrically catalizing a reaction is the current flowing through a given area of chemical. If this reaction is as fast as mentioned in the patent, then a larger area with closer spacing between anode and cathode and lower voltages should be tried first, before going to potentially lethal voltages. I hope to do some experiments with this process to. I will be looking forward to your results, Joe.

RE: [Biofuel] Burning glycerol for heat / Acrolein
Nitrogen is not explosive, infact it is used as a non flamable protective gas where oxidation is to be prevented.

Re: [Biofuel] I need filters
Hello to all: Thought I would put out how I have been filtering WVO. First I should say that my wvo is very clean and lightly used. One day or at the most two days and filtered on the job. It starts as pure degummed corn oil with no addatives and comes from COSTCO. I collect it and let it settle for a month or so. At which point it is very clear and brite. Some dark carbonated flakes or dust sized particles have settled out. I bought a dual canister water filter from a local hardware store. About 30$. The filter elements are of two types. Twenty micron synthetic yarn wound nominal 20 micron particulate filter, with no charcoal impregnation or any other special characteristics, 2 for 5$. The 5 micron filter is similar, also synthetic but not yarn wound, more like spun rayon or nylon fiber, 2 for 10$. These are household water filters, not oil filters so I don't really know what the micron size would really be. I'm just happy if they don't dissolve or become slimy. So far so good. I run the oil through the 20 then the 5 at a pressure of 60 to 80 psi and the oil flows at a rate of 40 liters in 12 minutes. The pump I used at first was a recycled pump from a carpet cleaner, steam extraction unit. This worked OK but I burned it out by accident. It only went to 50psi. I shopped for other pumps in Granger etc and everything was 2 to 400 $ for a durable hi pressure pump. Then I was at Kragen auto supply and there was a pressure washer on sale for 80$. It went up to 1300psi and claimed to be only usable for pure water. Well I bought one thinking I would try it and return it if it didn't work. I have been using it for 2 months so far. I leave it set up and with oil in it. I have a pressure tank with an air bladder in it. which I pump into. I manually regulate the pressure by turning the pump on and off by hand(sort of a pain) The only problems I have had are that it is not a great suction pump. It will suck oil from a depth of a few feet but only if there is no back pressure. So I have a few valves set up so that when it is priming, there is a free flow or oil back to the dirty oil vesel. I run the pump until all the air is out of the system then direct the oil to the pressure resevor and close the purge valve. So far I have filtered about 60 gallons or so with this pump setup. I only use about 5 to 10 gallons a week. I mix 50/50 with dyno diesel since my MB300TD is not converted yet. I have had no trouble with my regular stock filter, though I am getting ready to take a look at it to see if it is getting fouled. I think a used airless paint sprayer would also be a good bet for filtering. Thats my story and I'm stickin to it. ___ Biofuel mailing list [EMAIL PROTECTED] http://wwia.org/mailman/listinfo.cgi/biofuel Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuel archives at Infoarchive.net (searchable): http://infoarchive.net/sgroup/biofuel/

Re: [Biofuel] methanol recovery/first batch results
John, I am a novice at this too so others should feel free to criticize my remarks. I would suggest you titrate. This is not so easy at this stage because any free fatty acids in your fuel as you went into the base process are now soap, that is they are neutralized with Na.To convert them back to free fatty acids, I have taken say 10 ml of the product, and mixed it with vinegar strong enough to drop the pH back down to say 3 or 4. This will strip off the sodium. Separate this 10 ml of oil from the vinegar. Now you can titrate as if it were any waste or new oil. I think you are correct in assuming that you should have titrated in the first place. If you find that the free fatty acid is above 1 g/l equivalent NaOH then you will need to be careful when washing not to add much water to the first few washes. Check out the University of Idaho process. They use 5.5% to start out with and mix it up before the glycerin phase is separated off. Then settle for as long as it takes to get clear. But that process assumes you have the correct amount of NaOH or KOH added to your mix in the first place. Since you did not titrate first, you may not have added enough NaOH to neutralize the FFA's as well as catalyze the reaction. So the reaction may not have gone to completion. If you think that that is a possibility, You could always separate the glycerin, titrate as above, add 1/4 the original methanol and enough NaOH to both neutralize as well as catalyze. Then re-react. This second product will probably not drop any glycerin unless there was a lot of unreacted oil. I would probably let this batch settle and make a new batch with proper titration. You will learn from the new batch how to deal with the old.

Re: [Biofuel] Creating a cool room storage in a hot climate - solar.
Hi all, As I understand it, the nighttime sky looks like a 4 degree Kelvin source. (going from memory here) A well designed solar panel is insulated so that the ENERGY goes in and out only by RADIATION from the front and by CONDUCTION to the working fluid. ENERGY that leaves a black body (the solar panel) is balanced by the ENERGY coming to it when at equilibrium. If the panel was in outer space and not facing the sun it would cool down to 4 degrees above absolute zero when there was no heat input from the working fluid. Here on earth the atmosphere reflects heat energy radiated from the earth, back to the earth (the green house effect) so a perfect black body at night with a perfectly transparent window and perfect insulation would still not get down to 4 degrees K. But it will defiantly get well below freezing. In fact most solar panels need to be protected from freezing even in the summer.So it will make ice, the question is how much and is it worth the investment. If solar heat is needed during the day, then this would be an added use for the collectors. Air could be the working fluid and the thermal mass of the cool room could be the storage medium (instead of ice) then the system gets simpler.
