Some students at Wake Forest University in North Carolina used a
sugar based catalyst as a pretreat step before base
transesterification. Here are their blog posts on the results of the
experiment. (http://wfubiofuels.blogspot.com/)

What kind of sensor could i use for detecting when the processor is
full of wvo.
It is most common to use a load cell under your reactor vessel to
measure mass. You could also try an optical sensor that looked at the
level you wanted to fill your tank. You could also use a float switch

You might consider an ethanol distiller. Some nice ones are for sale

I do not know of any commercial biodiesel production via supercritical

Conclusions:
+ Need about 25" Hg vacuum
+ Need about 50 CFM
+ Need oil-less pump (methanol vapor washes oil from pump causing
failure)
+ Higher temperature is better
+ More air/mixing is better
+ Need liquid trap (mercury filled?)

Hi All (Keith, Alecs, Mike)~
I was searching through the archives and ran across a message (#4005)
that proposed a bucket test for glycerol content of home brew biodiesel
using borax. Has anyone experimented with this yet or come up with a
better backyard test?

I an acquaintance of mine is making ethyl esters in Congo and failed on
his first attempt. I think he just used too much NaOH. He has some very

Dear Group~
I feel like I'm missing a critical piece of information regarding FFA
and transesterification.
Ideal vegetable oil is triglycerides. Due to factors (like water
contamination, exposure to excessive heat, or long storage times) the
triglycerides can break into mono and di-glyceride
Ken, Keith, and Mark~
Thanks for the good information. Ken, I hope you're feeling better!
Below is the condensed version of what you taught me:
triglyceride = vegetable oil, three fatty acid tails bonded to one
glycerol
diglyceride = two fatty acid tails bonded to one glycerol
monoglyceride =
Does anyone have an MSDS for the roughly 80% pure glycerol we
homebrewers produce when making biodiesel that you'd be willing to
share?
