Dear Mr. Duarte Nuno Janu=E1rio:
I would advise to manufacture separately the WVO BD and Tallow BD. For =
sure it is easier if you use methanol.
Once you have the "biodiesels" I would add 80% WV BD + 20% Tallow BD, =
depending on temperature you want to use the blend.
Good luck,
Mr. F.J. Burgos

  Thank You Francisco

  
  I actually have a "tallow-problem-in-food-industry" to solve. I think =
that making biodiesel from it may be very nice and environmentally =
friendly solution.

  I'm beginning to produce my own biodiesel, I'm trying to do it with =
wvo first.

  Do you think that mixing tallow with vegetable oil could help to =
improve some of the "bad properties" of tallow?

  It would like to know some personal experiences about the proportions =
in which these two fats should be mixed.

    Dear Mr.  Duarte Nuno:
    one of the problems of obtaining BD from tallow is to have a =
consistent quality raw material. These days tallow is a little cheaper =
than a few years ago due  the existing surplus because the BSE "mad =
cows" ilness. It is advisable to work with "soap quality" tallow, 0.25% =
FFA, and also you should get rid of any moist on it.
    Yours truly,
    Mr. F.J. Burgos

      Hello everybody!

      

      Has anyone in this list ever tried to produced biodiesel from =
animal fat (tallow, for instance)?

      The process for vegetable oils is well known, but I don't seem to =
find much documentation on experiences on producing biodiesel from =
animal fat.

      From what I know, the problems with animal fat are the long chains =
of the fatty acids / triglycerides and the high level of saturation. =
This means that biodiesel produced from animal fat will tend to =
condensate, especially at low temperatures. How can one solve this =
problem?

      I would be very pleased if someone could help me on this problem. =
Any reports / papers or personal experiences are welcome!

      
      Thanks,

      
      
      Duarte Nuno
