Effectiveness of Homogeneous and Heterogeneous Catalyst on Biodiesel Yield: A Review

Abstract

Biodiesel is getting the attention of researchers due to its low cost and renewability. Researchers have done much work in the field of biodiesel production and its performance on engine. The effect of catalyst on transesterification reaction plays an important in terms of biodiesel yield and quality. Therefore, it is important to investigate the effect of catalyst quality and characteristics on transesterification reaction. In view of the same, the present paper deals with a review on effect of different heterogeneous and homogeneous catalyst on the biodiesel yield. The work of various past researchers has been compared. It is found that homogeneous catalyst gives better results in low temperatures however the heterogeneous catalyst needs high temperature for preprocessing however heterogeneous catalyst can be used again and again.
