Optimization study of binary metal oxides catalyzed transesterification system for biodiesel production

The focus of this study is to produce biodiesel using non-edible feedstock (Jatropha curcas oil) via heterogeneous base catalyzed transesterification reaction. The solid base catalysts, binary metal oxide (CaO–ZnO and CaO–La2O3) were selected for the transesterification of high acid jatropha oil. Fu...
