Esterification of Jatropha curcas hydrolysate using powdered niobic acid catalyst

In this study, free fatty acids (hydrolysate) produced from hydrolysis of Jatropha curcas oil was used for biodiesel production. The hydrolysate was esterified with methanol as the acyl acceptor in the presence of powdered calcined niobic acid catalyst. FT-IR analysis of the fluffy powdered cataly...
