Allen it sounds as though the reaction is incomplete. Animal fat can be tricky. i suspect that it doesn't obey the titration rule. Try retreating the batch with a 8gNaOH/50ml methanol per litre brew of methoxide, could take a while to dissolve the NaOH, may have to use more methanol. If this works up the NaOH level in subsequent batches. Used 16.7g of NaOH per litre to successfully process beef tallow. Figures seem ridiculously high but processed well.

[biofuel] Re: Processing animal fats
Paul, We are currently using the quantities suggested. Despite weeks of settling and boiling, we get what appears to be large quantities of soap at room temp, althoug with a small amount of heating ( to about 40-50 degrees C ) this soap appears to melt. Because of this I am not sure if it is soap or unprocessed fat. There is almost no trace of glycerine in the bottom, and only about 5% of the total volume in liquid biodiesel on top. This morning I tried to 'wash' a sample and when water was added the mixture became thick and white, probably the soap. --- In [EMAIL PROTECTED], "Paul Gobert" <[EMAIL PROTECTED]> wrote: > > - Original Message - > From: "awaideau" <[EMAIL PROTECTED]> > > > Has anyone had any success making biodiesel using only animal fats. > > If so I am after some advise on how to get the crap to work properly. > > Allan, would suggest using high levels of methanol and NaOH. > Have made BD from "Frytol", edible animal fat with 8g/L NaOH and 250ml/L > methanol. > Vigorous mixing and separating the BD and glycerine as soon as is practical > ( 1 to 2 hours then again at 24hrs) gives best results. > If you have problems with tallow/tallow ester dropout after the BD has stood > for a few days, freeze/thaw then filter the BD . > On subsequent batches up the ammount of NaOH. > > Regards, Paul Gobert. > > www.ozimages.com.au/profile.asp/MemberID=517 Yahoo!
