Comparision of Biodiesel Production From Karanja Seeds, Jatropha Seeds and Thumba Oil

The transesterification process was carried out for karanja oil seed, jatropha oil seed and thumba oil by using alkali catalyst KOH. The properties of biodiesel like density, viscosity, flash point, pour point, cloud point was compared with conventional diesel at 70⁰c. The Effect of temperature on karanja oil methyl ester (KOME), jatropha oil methyl ester (JOME) and thumba oil methyl ester (TOME) were studied and yield for karanja, jatropha, thumba methyl ester was obtained 85%, 86%, 81% respectively. Maximum conversion of the methyl ester was achieved at 0.3 (v/v) methanol/oil ratios for karanja oil seed, jatropha oil seed, thumba oil.
