Abstract

Summary

A two step process consisting of esterification and transesterification was developed to produce biodiesel from crude
waste ube fruit oil. The oil was extracted from the waste ube pulp using solvent extraction process. The free fatty acids
(FFA) in the oil were converted to methyl esters in the pre-esterification step using sulphuric acid as catalyst. The FFA
was reduced from 77.84% to below 1% in 2hours under 10wt% of methanol, 1wt% Sulphuric acid in oil at 600C. The
yield of biodiesel by transesterification was 95.5% in 60minutes at methanol/oil ratio of 6:1 at temperature of 600C, KOH
catalyst ratio of 1% and reaction time of 60minutes.
