Hi All I have access to a source of animal fat that is used for deep frying I have tried to make biodiesel from it but only succeed in producing a very soapy gloop I used the ratios from Mike Pelly's reciepe Is there a difference between using animal fat and wast veggie oil? HelpSend instant
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

Speaking of animal fat, I have been
approaching quite a few grease traps lately to discover that most of them are
filled with thick white grease. It is impossible to pump up as it isn't in a
liquid format. As well, even if I was able to obtain the liquid, how do I know
if it is animal fat
Hi you all
The investors team have defined we will start our industrial biodiesel
production and fuel production using animal fat. I have gone thru
several sources and found very litllte info and literature about
production strating from animal fat. Can you folks help me on this??

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

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
I have been making biodeisel from WVO for a few years, running a diesel car, a
boiler and three tractors. I have used the single stage method to make several
thousand litres without a problem. I have recently been offered a significant
quantity of animal fat (in Australia Frytol), and while
Saria Bio-Industries of Germany has built the world's first animal biodiesel
plant with a capacity to produce about 10 million liters per year.
Cow carcasses are the primary feedstock, from which fat and meal are extracted
and separated. The fat is converted into biodiesel using a process that
