Studies on Characterization of Raw Jatropha Oil and its Biodiesels with Relevance of Diesel

Abstract

-Biodiesel is a renewable fuel as an alternative to petro-diesel fuel consisting of the alkyl monoesters of fatty acids derived from vegetable oils and animal fats. The utilization of biodiesel produced from jatropha oil by transesterification process represents one of the most promising options for the use of conventional fossil fuels. The high FFA content raw jatropha oil of was converted into jatropha methyl ester (JME) and ethyl ester (JEE) known as biodiesel in presence of acid and alkaline catalyst with methanol and ethanol respectively. The fuel characteristics properties of diesel, raw Jatropha oil, its ethyl and methyl esters and blends of diesel-esters in 80:20 ratio like relative density, kinematic viscosity, gross heat of combustion, cloud and pour point, flash and fire point, conradson carbon residue, ash content and total acidity were determined for its compatibility as CI engine fuel and it was found that esters and its blends have fuel properties close to that of petro-diesel. However, the conradson carbon residues of jatropha oil and their methyl and ethyl esters were higher than that of petro diesel.
