Kinetics Study of Transesterification of Karanja and Rice Bran Oil

Transesterification reaction of Karanja oil and Rice bran oil with methanol was performed by using ZnO as catalyst. The reaction was carried out in the batch-type reactor at 55-65°C and atmospheric pressure. It was consequently demonstrated that, in a preheating temperature of 55-65°C. It was observed that with increased in temperature from 55 to 65°C, the concentration of biodiesel increased. It was found that the highest conversion of biodiesel was obtained at temperature 65°C and lowest at 55°C.The kinetic study of reaction including order and rate of reaction and activation energy ( Karanja and Rice bran oil ) was calculated.
