摘要：

The present experiment examines the production of biodiesel from Jatropha curcas Seed oil having high free fatty acids (16.4 % FFA). The high FFA level of Jatropha curcas Seed oil was reduced to 0.23 % FFA for Jatropha Methyl Ester (JME) and 0.27 % FFA for Jatropha Ethyl Ester (JEE) by a two step acid-base transesterification. The first step was carried out with 10 : 1 molar ratio of methanol/ethanol-to-oil in the presence of sulphuric acid as an acid catalyzed at a temperature of 60 +/- 1 degrees C and 70 +/- 1 degrees C for methyl esterification and ethyl esterification respectively. The second step was transesterified using 6 : 1 molar ratio of methanol/ethanol-to-oil and 3 % w/w KOH as an alkaline catalyst to produce biodiesel at 60 +/- 1 degrees C and 70 +/- 1 degrees C for jatropha methyl ester and jatropha ethyl ester respectively. The yield of jatropha methyl and ethyl ester under the optimized condition was found to be 97 and 95 percent respectively.
