Application of Potassium Impregnated Calcium Oxide/Magnesium Oxide Catalyst for Transesterification of Jatropha Curcas Oil with Methanol

Abstract

Biodiesel is the name of a clean-burning, non-toxic alternative fuel made from vegetable oils and animal fats that can be used in compression-ignition engines. It refers to a diesel-equivalent, processed fuel derived from biological sources [1]. Biodiesel, which is mostly produced from vegetable oils, is mono-alkyl ester and is perceived to replace the diesel fuel [2]. Biodiesel fuel (B100) burns much cleaner than petroleum fuel due to its oxygen content. The exhaust emissions of sulfur oxides and sulfates, the major components of acid rain are essentially eliminated compared to diesel. Biodiesel is comprised of mid-carbon chains, which burn more completely than petroleum fuel. That is why there is a substantial reduction of unburned hydrocarbons, carbon monoxide, and particulate matter compared to emissions from diesel fuel. Biodiesel has exceptional lubricating qualities. Use of biodiesel or biodiesel blends have been shown to contribute significantly to the longevity and cleanliness of diesel engines. In new engines, biodiesel fuel consumption is similar to that of petro-diesel. In used engines, fuel economy substantially improves due to continuous cleaning effect of biodiesel.
