Hi Tom
Let me see if I 've got this right. BD made with Animal
fat solidifies at a higher temp than WVO? This could be handy info as a lot of
the chippies here use lard.Fortunatley I think I've got onto a source of
WVO. Diesel prices in NZ are now a $1 pL for your interest

Hi Ian and Theresa,
Definitely have to agree with Todd here. I´ve been doing a lot of work
making BioD from animal fat. It resolidifies at relatively high temperatures.
I left 2 liters in a hood in my lab over winter break. They turn off the heat
here cause we rarely get freezing temperatures. We have a few days down to
about 5 degrees C and some as high as 22. When I returned to the lab it was
chilly again and the BioD was a yellowish white solid. With the heat on the
last two weeks it´s liquified and looks just like it did originally but I
haven´t engine tested it yet to see if it still really is BioD.

how long Biodiesel will keep after production.
Keep it in an airtight
vessel with only enough head space for thermal expansion and contraction
and it will be sufficient beyond this time next year. More probably well
beyond that. At least long enough for the fallout to settle, a season's
worth of rains to soak it in and you to plant another crop so you can do
whatever it is that you feel you must do that can't be done without an
infernal combustion engine.
Spec it to10 microns filtration and be
happy. After that, it's not the sediment that will grab you by the short
and curlies but the saturated esters (from animal fats and hydrogenated
oils. Depending upon the parent stock, your filter could be throttled by
"B-100" at temps as high as 40*F.
Last time we rendered deer
tallow and made biodiesel from it we were stonewalled after an overnight
temp of 56*F.
