Studies on biodiesel produced from Jatropha oil in Cambodia by a non-catalytic using C2H5OH

Abstract

Different technologies are currently available for biodiesel production from various kinds of lipid containing feedstock. Among them, the alkaline-catalyzed methods are the most widely studied. However, here are several disadvantages related to biodiesel production using alkaline catalysts such as generation of wastewater, catalyst deactivation, difficulty in the separation of biodiesel from catalyst and glycerin, etc. To limit the problems mentioned above, in this study, biodiesel is produced by a non-catalytic using C2H5OH. The effect of experimental variables (the molar ratio ethanol/oil of 41.18:1 – 46.82:1, reaction times of 50 - 90 minutes and reaction temperatures of 2750C - 2950C) on the yield of biodiesel was studied. The 96% yield of Cambodia biodiesel of reaction between C2H5OH and Jatropha Oil at 46:1 at temperature 2900C at 60 minutes no using catalysts. Obtained biodiesel fuel was up to the International Standard ASTM D6751 for biodiesel fuel blend stock (B100).
