Re: [Biofuel] Ethyl esters biodiesel - Lee - was (no subject)
Keith: I successfully ran a test batch using the heads and middle portion of the distillation (light alcohols and ethanol). The wash test and methanol tests showed a complete conversion. I used 28% alcohol by volume. The more dilute tails go in a barrel to be run again at a later date. I recently built a 25 gallon compound fractionating still. Soon I will put it in to operation to make 96% pure ethanol in volume. Lee. -- next part -- An HTML attachment was scrubbed...

Keith: Thanks for responding. I do a second distillation using calcium chloride and then 3A molecular sieve to dry the alcohol. So far I have been using 50% lard mixed with 50% soybean oil (both used) . I am in the process of eliminating the lard and using used soybean oil with a titration of 2 grams NaOH per liter. I use KOH at the U. of Idaho's recommended amount of 1.3 Kg per 100 liters of oil. I have been using 1/3 purchased methanol mixed with 2/3 self produced ethanol and using 20% alcohol by volume in the reaction. The ethanol is 99% pure.

[Biofuel] (no subject)
I have been making biodiesel using ethanol for about a year. Methanol is $500 a barrel in Hawaii. I'm having some difficulty with partial conversions with substantial vegetable oil remaining dissolved in the ethyl esters demonstrable by the methanol test. I have been using 99% alcohol I make from sugarcane that I grow. I am currently using all distillation fractions including the light and heavy alcohol portions. Any thoughts on whether it would be better to use only the ethanol fraction in order to encourage more complete conversions? Lee -- next part -- An HTML attachment was scrubbed...
