Increasing reaction temperature enhanced the yield of biodiesel and shortened the reaction completion. According to shrinking core model, the mechanism of in-situ methanolysis of Jatropha curcas was chemical reaction control with the first-order reaction. The constant of the first-order reaction rate in the range of 5.15�10-9 to 8.78�10-9 m·s-1 and Arrhenius activation energy of 22.66 kJ�mol-1 were obtained. © 2014 Trans Tech Publications, Switzerland. %D 2014 %R 10.4028/www.scientific.net/AMM.625.306 %O cited By 1; Conference of 3rd International Conference on Process Engineering and Advanced Materials, ICPEAM 2014 ; Conference Date: 3 June 2014 Through 5 June 2014; Conference Code:114811 %J Applied Mechanics and Materials %L scholars4716
