OK, Since we're on the subject, I've been wondering where I can purchase the H2SO4 necessary for this process. Can anyone give me some direction? Mike

Others have. Producing ethanol from cellolose by acid hydrolysis is a long-established method still used all over the world, and it's still the only method available to backyarders, though that could change anytime with new enzymes and new techniques being developed. Maybe Pannir will change it. Otherwise you have to use sugar or starch crops (or wastes), ferment it, distill it and dry it. If you're not going to mix the ethanol with gasoline there's no need to dry it. If you want to experiment with ethyl esters biodiesel you do need to dry it. >Well, IF I succeed this time, how can I now the % of ethanol and water ? >I have zeolite, so I should be able to dry the ethanol.

It means a bit of the previous message has been cut. Previous material that's not important anymore should be snipped and marked , it saves bandwidth and improves communication.
