Production of Biodiesel using Homogeneous Alkali Catalyst and its Effect on Vehicular Emission

Abstract

Biodiesel fuels offer a potentially very interesting alternative to conventional diesel regarding reduction in harmful emissions in addition to engine wear, cost and availability. The present work has focused on the production of biodiesel using Jatropha oil as a feedstock via homogeneous alkali catalyzed transesterification route, overall kinetic rate expression development and study of emissions from diesel engine using produced biodiesel in the Study. The catalyst used is KOH. The production of the biodiesel was at the laboratory scale. Quality checking of the prepared sample is covered. Overall kinetic study and performance of B20 and B40 on the diesel engine was also performed. The results show that the yield of the biodiesel using Jatropha oil is 86 %. The emission of the air pollutant like SO2 and SPM is decreases with the different biodiesel blends with different proportion without major changes in the engine performance.
