Abstract

A two-stage process (esterifi cation followed by transesterifi cation) was investigated in biodiesel production from mixed crude palm oil (MCPO) having high free fatty acid (FFA). For the required methyl ester content greater than 96.5 wt%, the two-stage process could produce biodiesel obtaining 95% yield under a molar ratio of 10:1 of methanol to FFA and 10 wt% of sulfuric acid based on FFA, and a molar ratio of 6:1 of methanol to initial triglyceride (TG) and 0.6 %wt/v of sodium hydroxide based on the initial TG at 60 ºC with a total production time of 11 hr 35 min.
