Abstract

Raw material and processing costs are adversely affecting the economic viability of biodiesel technology. In-situ transesterification of non edible oil seed particles such as jatropha curcas can minimize the costs of feedstock, oil extraction and purification; slow conversion rates due to limited solubility of oil in methanol can be enhancedby using phase transfer catalysts; microwave pretreatment of seeds can make oil molecules more reactive. In the present work, these three concepts were utilized together to investigate in-situ transesterification of microwave pretreated jatropha curcas seed particles in the presence of alkaline phase transfer catalysts (PTC) such as cetyltrimethylammonium bromide (CTMAB), benzyltrimethylammonium hydroxide (BTMAOH) and crown ether (CE); BTMAOH was observed to be better than CTMAB and CE. It was observed that use of alkaline BTMAOH as a PTC and microwave heat pretreatment of jatropha curcas seed particles have substantially increased the reaction rate of in-situ transesterification reaction.
