No real difference between the two, at least not relative to making fuel.
The suggestion would be to use KOH instead of NaOH for starters. That
should help end your thickening/soap issue.
Don't jump the gun with large batches until you get the small stuff
right if you're still having problems.
Animal fat (tallow) has a different chemical make-up than vegetable oil.
You need to do much more purification. You get soap (glycerin) like
results with vegetable oil, just not as much. I think that if you use a
stronger caustic agent to separate mixture components, you may have more
success.
Tallow, lard, butter, vege oil, etc. are all the same chemically save
very, very minor differences which don't impact the transesterification
reaction. fats and oils are treated the same as to volume of methanol,
reaction time, and amount of catalyst. Impurities, mainly water present,
will
Stronger caustic agent? As in NaOH vs KOH?
You're aware that saturated phats and oils tend to make harder soaps and
that NaOH contributes to that end even further?
Using the general method of self-mixing the methanol and caustic, as
most grassroots and small scale brewers do, there is also the
I have processed 100% virgin beef tallow fat with the 2 stage base - base
process
with great sucess. I used 200 ml methanol / liter fat and 6.7 g NaOH
Processed for 2 x 2hours at 58 - 60 deg C.
That batched washed better and easier then any other WVO I had dealt with
The only drawback is cold

I think you should experiment with some small
batches. I get some of my oil from restaurants that fry meat and think 1/3 of
the stuff is animal fat. I seperate this thick gravey like stuff from my less
viscousoil and heat it up firstto liquify it real good before I do

I went to a biodiesel convention and saw a booth on animal fat
conversion to biodiesel, the process is called rendering.

There is quite a lot of information about.
Just do it, it's no big deal.

James,
Doing a careful titration is very important when using
a new oil source. Animal fats require more base
catalyst. Acid/base is the best way to go for optimum
yeild and minimal soap.

I don't know if you'v mentioned this method yet but it might be worth a try
it's not for novice biofuel makers.

It would be worth discussing it with Kieth Addison before attempting it. I
think you'll find he's very patient and
can imagine beef tallow lard is a very cheap raw material (250 u$s per ton)
and quite esasy to purchase. I 've made only 1 essay and my results havent
been as I first expected. Please, if its not a big deal for you, let me know
about your progress. Please, forgive my English. Best regards and
fats measure high on tritration, but I've tempered this by using 50/50
WVO and animal fat. This lowers the titration. The down side is the
yeild isn't as high as WVO.
The method I use is the single base method.
I haven't tried a acid/base method yet.
Let you know my results
