Re: [biofuel] methanol production/corncobs
One of our project members has requested that I investigate the possability of methanol production using corn cobs as a feedstock. Consisting of mainly cellulose I imagine that a destructive distillation might be the route to go. Does anyone have a lead for more information on destructive distillation or related material? I am more inclined to use pulverized corncobs as Biodiesel production power myself but a small scale methanol production unit would definately lower our projected costs of Biodiesel production. Dana Linscott Hi Dana Why not go for ethyl esters? Re methanol, there's some information in the message archives. Try a search for Hynol, destructive distillation, DD, should work. We haven't found anything satisfactory. There was a method in a Home Power article mentioned (Jerry?), but I don't think anybody's tried it and I don't have a detailed description of it. Do you need to expend the power pulverising the corncobs for BD production? Couldn't you burn them as-is?

Maybe when they complete their work but right now it's a waste of time. Sounds like someone is milking the gov for grant money. The Home Power Mag DD to methanol article is looking better as I've read other stuff that it will work. How to purify it is another question. It's on their 1st CD. If you just need heat a producer gas unit may be good for you or just burn the cobs like Keith said. Serveral good producer gas units on Keith's and Steve's sites. jerry dycus Best Keith Addison Journey to Forever Handmade Projects Tokyo http://journeytoforever.org/ __ Do You Yahoo!? Yahoo!

Funny you should mention this. The French distillery manual that I mentioned in an earlier post says that methanol obtained in destructive distillation is from the lignin in the wood, so corncobs don't sound like a good source of methanol. I checked in Hgglund's _Chemistry of Wood_, which says the same thing. On the other hand, you can get fermentable sugars from cellulose by hydrolysis, and ferment those to get ethanol. You'll need to do some experimenting, starting with processes designed for high-cellulose waste such as cotton linters. Ethanol from cellulose, methanol from lignin. It turns out that you can get both fermentable sugars and methanol from the same woody feedstock by first saccharifying (hydrolyzing) woody waste, then destructively distilling the residue. You can also get methanol from the residue of paper production - Hgglund concentrates on sulphite (acid) process residues, but I believe this is also true of the residues of the alkaline or sulphate process. This is especially nice as those residues are a serious pollution source.
