Heterogeneous Catalysts for Biodiesel Synthesis from Karanja Oil by Transesterification Process

Abstract

The heterogeneous catalysts are playing an important role and are perspective catalysts in future for biodiesel production. These heterogeneous catalysis features lower corrosiveness, environmental friendliness, easy catalyst recovery and high process integrity, all at levels superior to those of homogeneous catalysis. The heterogeneous basic catalyst includes oxides of Magnesium, Aluminum and Calcium etc. All sort of experiments were conducted by using the engine. The performance and emission results obtained were analyzed and discussed. The different blends of Karanja Biodiesel were compared with fossil fuel diesel. From observations it could be concluded that the blends of Karanja with diesel up to 20% by volume could replace diesel for running the diesel engine with less emissions without modifying the engine and without sacrificing the power output. This will thus help in controlling air pollution to a great extent.
