Abstract

Summary

The production of biodiesel from waste ube oil was carried out through a two step process of esterification and
transesterification reaction. The kinetics of the esterification of free fatty acid (FFA) in the waste ube oil with
methanol, in the presence of Sulphuric acid at concentration of 10wt% relative to free fatty acids as catalyst
concentration and methanol/oil ratio of 10:1. The energy of activation for the forward reaction decreased with
increasing catalyst concentration from 4006.41 to 1346.15J/mol. The FFA was reduced from 77.84% to 0.97%
in 2 hours. The kinetics of transesterification was studied with the model developed and simulated to give a
result of 95.5% molar yield of biodiesel at reaction time of 60 minutes under catalyst concentration of 1%,
methanol/oil ratio of 6:1 and temperature of 550C.
