摘　　要：在固定床反应器内进行了甲醇制烯烃反应动力学研究,借助集总动力学的概念,充分考虑到水和积炭对反应过程的影响,建立了5集总反应动力学模型,并进行了求解,最终获得了新鲜催化剂上可计算各集总组分反应速率的动力学方程。模型计算值与实验值吻合较好,表明模型预测效果很好。The kinetics of methanol to olefins in the fixed-bed reactor was studied. The lumping idea was introduced into the kinetic study, in which the effects of water and coke deposition on reaction process were fully taken into consideration. The five-lumping kinetic model was established and the reaction rates over fresh SAPO-34 catalyst were calculated. The finally obtained general kinetic equations over fresh catalysts could be used to calculate the reaction rate for each lumping component, and the calculated values had a good agreement with experimental values.
