Use this calculator to help determine your biodiesel recipe
If you have performed an acid number test, you can input your data to get an acid number and % of FFA or you can directly input a % FFA to arrive at the catalyst you need.
Titration value =
Blank value =
Normality of KOH =
Weight of sample in grams =
Fatty Acid Profile mostly... Oleic, Palmitic, or Steric Lauric
Calculation:
(The numerator is the Acid Value, the entire fraction is % of FFA)
(( - ) * ( )* 56.1 / )
Acid Value = In mg KOH/g sample
% of FFA =
Use this calculator to determine how much catalyst you need for your biodiesel reaction
Sample size (Grams) =
Catalyst Type Sodium Hydroxide Potassium Hydroxide Sodium Methylate
% NaOCH3 in MeOH (Only for sodium methylate) =
(( * ( * )) + )
100
Catalyst Amount (Grams) =
Recommended Extra Catalyst Amount (Grams) =
