Abstract

Biodiesel is produce mainly by transesterification, reacting vegetable oils or animal fats with monohydric alcohol in presence of a catalyst. The transesterification reaction is affected by various parameters. One of this parameter is catalyst type. Generally, catalysts used in transesterification reaction can be divided into three categories: homogenous, heterogeneous and enzymes.  Heterogeneous catalysts offer numerous advantages over homogeneous catalysts as it can easily be separated from reaction mixture and can be reused, possess high thermal stability, have limited corrosion effect, and easily applied in continuous processes. Preparation of heterogeneous base catalysts derived from commercial chemicals sometimes consists of multiple complicated steps. As a result, those catalysts might become uneconomical, especially on a commercial scale.
