Hi David R. Thank you for taking the time, and I agree on the small plant scenario. I will try to get the first book you mention asap. There is some good info at www.britannica.com . I started out by just entering glycerol, and that is a short entry, three paragraphs, but at the bottom of the paragraphs it says * click here for more info * . That takes you to " soap and detergent " the third paragraph in that is very interesting as it tells how to separate the glycerin from the soap with a saltwater solution. If you have time check it out. The people at www.arserrc.gov filed for a patent ( 08/631,498 ) on 4-12-1996 for a process for "Biodiesel Production with Lipases" and they also were working on a process for " Soapstock for Biodiesel Production ". I tried to find the patent I mentioned at www.uspto.gov but couldn`t locate it . The website says that for a fee you can get a copy of the patents and get a license to use them. I was very aggravated in not being able to find any more info! The soapstock thing sounded terrific ! I also found that the NREL in Colorado also has this technology, the process with the lipase catalyst . I`m sure a lot of us would like to know the details on both these things, especially the soapstock process !!
