Potensi Katalis γ-Alumina Tersulfonasi Terhadap Kadar FFA Sisa Pada Proses Esterifikasi Minyak Biji Karet

Abstract

ABSTRACT

Biodiesel is usually made by the transesterification process using an alkaline catalyst, but oils with high free fatty acid like rubber seed oil use the esterification process.This study was investigate the capability of a heterogeneous catalyst γ-alumina sulfonated acid at remainFFA of esterification reaction.The variation this research are ratio of methanolto oil (v/v), ratio of catalyst to oil (w/v) and reaction temperature on esterification reaction of rubber seed oil. The results showed that the operating conditions to give the smallest FFA content are the ratio of oil to methanol 1.2 v/v, the reaction temperature  60 ° C and the ratio of catalyst to oil 1.67%-w/vuntil 4.5 hour.
