摘要
Methyl esters were produced by trans-esterification of c ottonseed oil with methanol in the presence of a homogeneous catalyst (KOH).A ki netic model was established by taking three consecutive and reversible reactions into consideration.Rate constants were determined for each reaction by the Rung e-Kutta method with optimization.The corresponding values of frequency factor a nd activation energy were then obtained based on the Arrhenius’ law for a ll forward and reverse reactions under different experimental conditions.
Methyl esters were produced by trans-esterification of cottonseed oil with methanol in the presence of a homogeneous catalyst （KOH）. A kinetic model was established by taking three consecutive and reversible reactions into consideration. Rate constants were determined for each reaction by the Runge-Kutta method with optimization. The corresponding values of frequency factor and activation energy were then obtained based on the Arrhenius＇ law for all forward and reverse reactions under different experimental conditions.
