Re: [Biofuel] methanol recovery from fuel stock?
Thankyou Ken, succinctly put, as ever. Best Keith On Nov 4, 2005, at 10:11 PM, Ken Dunn wrote: I'm still a bit confused. What is the trick to evaporating the methanol without reversing the process? Very simple -- you can't boil off methanol when both biodiesel and glycerine are present without shifting the equilibrium backwards to some extent. You can recover methanol out of a mixture of methanol with biodiesel, or out of a mixture of methanol with glycerine, but NOT out of a mixture of all three. -K ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
Re: [Biofuel] Information in Japanese
Hello Nicholas Greetings, I am in Japan and would like to 'inform' my Japanese father-in-law about the biodiesel process. Is there any information available? The terminology is rather specific and my Japanese isn't the best... Any help would be appreciated. Nicholas At the bottom of all the pages at the Journey to Forever website there's a link to Midori's Japanese Journey to Forever website, find your way from there to the biodiesel section: http://journeytoforever.org//jp/index.html Midori also runs a Japanese Biofuel mailing list, sister to this one. We hold regular seminars on biodiesel here in Tamba, very intensive four hours, people come from all over Japan. Dates of the seminars are announced in advance at the Japanese website and the mailing list.

Re: [Biofuel] Power Compost!
Robert, I'm not sure what type of engine you have, but an option might be to modify it to use ethanol and then delay the timing to get higher compression. That may result in a more efficient system. You would have to have a supply of ethanol though and you may not be able to delay the timing if its a magneto style engine (can one delay timing on a magneto?) A friend of mine recently donated a shredder for my use. After rebuilding its carburetor (hateful things, carburetors!) and re-lapping stuck valves, changing gaskets and cleaning GUNK out of the fuel tank, it's running fairly well again. (It still needs a replacement throttle return spring, but I'm trying to solve one problem at a time . . .) You could buy the horse and feed it the cornstalks and compute your milage based on that! Of course, the same thing could be said of rototilling. I'm certainly not going to invest in one of those tiny horses I've seen around here to do that job for me. robert luis rabello ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
Re: [Biofuel] Power Compost!
It should be relatively easy to modify the ignition timing on a magneto driven lawnmower type engine. The magnets are usually on the flyweel/blower on top of the engine (or the other end from the drive shaft, for horizontal shaft engines). They trigger the magneto which is fixed to the engine block. I guess it actually sparks during the end of the exhaust stroke too since it's on the crankshaft instead of the cam? If you could adjust the positioning of the trigger magnets on the block, or rotate the flyweel in relation to the crankshaft by modifying the keyway, you could adjust the spark timing. We would always hit stumps with our little lawnmowers, which slowly shears the flywheel key off, and eventually the ignition gets too far out of time for the engine to run any more so you have to take it apart and put a new key in. Adjusting valve timing is harder, since these usually use a 1:2 gear reduction. You could shift it one tooth off, but this is probably about 20 degrees -- too much I think, and you really need to be able to adjust the intake and exhaust valve timing separately. Regrinding the cams could also work, but that's probably way more work than is justified for a little gas engine. Even more work than milling the head. I'd be tempted to run it from biodigester gas. That should only require replacing the carbureator with a relatively simple air/biogas mixer, and probably derating the horsepower a bit based on the heat content of the biogas.

I'd like to run ethanol in my truck! Getting higher compression out of a Briggs and Stratton engine would involve milling the cylinder head. For the amount of time the shredder will be used every year, that hardly seems to justify the machine shop expense. I've also seen tiny turbos in my internet meanderings, and while installing one of those would be really cool (Robert's turbo shredder!), I'm probably better off to swap the engine with an electric motor when it dies. You could buy the horse and feed it the cornstalks and compute your milage based on that! Then I wouldn't need the shredder, would I? robert luis rabello The Edge of Justice Adventure for Your Mind http://www.newadventure.ca Ranger Supercharger Project Page http://www.members.shaw.ca/rabello/ ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/ ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
