I looked but I don't see enzymes. Can you reference the message ID numbers? I can only find quotes saying there is information and not the information.
Thanks Andy "Hello JanI don't think the Biox process claims to use lipase. Seems to use just about everything else though, except a pinch of salt maybe.Lipase catalysis is an established biodiesel production method, with quite a few advantages, and some disadvantages, but not done on a backyard scale yet, though quite a lot of people are interested in that.BestKeith" In your email with the subject re:enzymes I found: " added an inert cosolvent to the base-catalyzed methylation of vegetable oils to speed the reaction time."Before this discovery, it took anywhere from two to four hours to complete the biodiesel manufacturing process," Boocock says. "By adding an inert cosolvent, such as methyl t-butyl ether, to the process we produced methyl esters from vegetable oils in seven minutes" On Sat, 15 Jan 2005 04:32:59 +0900, Keith Addison <[EMAIL PROTECTED]> wrote: > >Keith, > > > >Is ":-) I'd suggest you check on whether the process is watertight before > >you start bothering about the reactor.
