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.
