Abstract

Development of biodiesel production using methyl tertiary-butyl ether (MTBE) as a co-solvent for the esterification of palm fatty acid distillate (PFAD) has been investigated. The PFAD with a high free fatty acid (FFA) was used as a potential feedstock due to it is a low price and non-edible. The effect of reaction parameters i.e. molar ratio of methanol to FFA, catalyst concentration, reaction time and amount of co-solvent on FFA conversion were studied. The results showed that 98.37% FFA conversion obtained under the condition: 7:1 molar ratio of methanol to FFA, 8 wt.% sulfuric acid, 45 min reaction time and 17.5 wt.% MTBE. Moreover, the presence of co-solvent can be improved the FFA conversion and glycerides conversion leading to increase in ester content of 4.8 wt.% when compared without co-solvent system.                        Keywords :  biodiesel, palm fatty acid distillate, co-solvent, esterification
