摘　　要：采用积分反应器考察常压下Y型分子筛上甲醇脱水生成二甲醚的反应动力学。根据甲醇脱水反应机理和R-E、L-H反应历程,推导出四种甲醇脱水动力学方程。通过对试验数据的拟合,确定在Y型分子筛上甲醇脱水生成二甲醚的六参数反应动力学方程,方程计算值与试验值吻合较好。The kinetics of methanol dehydration to dimethyl ether （DME）over zeolite Y was studied in an integral reactor under atmospheric pressure. Based on the reaction mechanism of DME produced from methanol dehydration, four kinetic equations are obtained according to the Langmuir- Rideal （Rideal-Eley）mechanism and Langmuir-Hinshelwood mechanism. A six-parameter kinetic model of methanol dehydration to dimethyl ether over zeolite Y is obtained by data processing,and the calculated values are in good agreement with the test data.
