甲基磺酸催化高酸值地沟油酯化反应动力学研究

Esterification kinetics of waste cooking oil with methanol in the presence of catalyst methanesulfonic acid were determined．in the experiments， methanol were continually pumped into the waste cooking oil，water and unreacted methanol were distilled simultaneously．The results showed that the reaction was a first-order model，activation energy of esterification was 76.06 kJ/mol，Increasing catalyst amount 、methanol flow rate and reaction temperature were beneficial to improve the reaction rate．
