Abstract
In this study, the production of biodiesel by transesterification of castor oil with methanol in the presence of alkali catalyst was studied. The reaction parameters such as catalyst type (potassium hydroxide, sodium hydroxide, potassium methoxide and sodium methoxide), reaction time (540 min) and reaction temperature (2565 °C) were optimized for production of castor oil methyl ester. Finally, analytical methods were applied on the final biodiesel product to determine the fuel characteristics and results were compared with the diesel standards of EN 14214 and ASTM D 6751. The present study indicates that castor oil is quite suitable for biodiesel production.
