Abstract:

 Feasibility of biodiesel (BD) production from non edible Jatropha Curcas oil (JCO) using different enzymes as catalyst has been studied. BD is considered as non-conventional, alternative, renewable, green energy sources. Optimum production of BD from JCO is directed by the initial characteristics of raw materials along with important reaction parameters like reaction temperature, concentration of enzyme as catalyst, reaction time and molar ratio of initial raw materials. Enzymes play an important role in the transesterification reaction for optimum conversion of BD and in the present research investigation, the effect of variation of enzyme for the production of BD from JCO has been analyzed. Four enzymes namely NS 435, TLIM, RM IM and NS40013 (6%) have been studied in the presence of solvent at 6:1 molar ratio of alcohol to JCO maintaining a temperature of 600C with 600 rpm of mixing intensity for 8hrs. The research findings show that NS 435 is the most efficient enzyme and contributes highest yield of BD through transesterification reaction between JCO and methanol compared to other enzymes. The properties of Jatropha methyl ester are measured and are in conformity with the ASTM standards.
