Preparation of Biodiesel from Karanja Oil using Homogeneous and Heterogeneous Catalyst

Abstract

In India, diesel consumption is increasing at an alarming rate which is increasing the import bill and the problems related to environment pollution. Biodiesel (BD) from non-edible oil like karanja is attractive feed stock for diesel engine. Due to high acid value of karanja oil (KO), a two-step process is necessary for BD production using homogeneous catalyst. In present study, BD was produced from KO by transesterification process using homogeneous catalyst (KOH) and heterogeneous catalyst (CaO) by two-step process. A catalytic characteristic of CaO was improved by loading lithium on CaO. Prepared Li-CaO was used to produce BD from KO in single step simultaneous esterification and transesterification process.
