Abstract:

We have studied transesterification of Jetropha oil with heterogeneous catalyst and found that the heterogeneous catalyst HPA with alumina support worked very well for transesterification of oils.  The maximum conversion was above 70% and the GCMS analysis showed that the biodiesel consisted of ten major products viz. Methyl Palmitate, Methyl Stearate, Methyl Oleate, Methyl Linolenate, Methyl Linoelate, Methyl Eicosanonate, Methyl Archidate, Methyl Tetra deconate, Methyl Pentyl hexonate and Methyl Behenate.  They were found to be present in all oils however their concentration were different for different oils.  The first order plots were found to fit the conversion versus time data as well as the yield of different components of the biodiesel versus time data.  The catalyst activity remained unchanged at least for 1000 h.
