Abstract

PURPOSE: In preparing an olefin from methanol and/or dimethyl ether, to reduce the amount of a diluent used, to improve rate of reaction and selectivity, to prevent a catalyst from deteriorating, by reducing rate of feed of a raw material per crosssectional area of catalytic layer and per hour.
CONSTITUTION: Using a catalyst comprising crystalline aluminosilicate zeolite (e.g., FZ-1 zeolite, etc.), olefin is prepared from methanol and/or dimethyl ether by a catalytic reactor of fixed bed. In the reaction, methanol and/or dimethyl ether are fed in amounts in range from 0.3W15g per sec per crosssectional area of catalyst, and the amount of a diluent used is reduced. The heat of reaction produced per crosssectional area of catalytic layer in a direction perpendicular to the direction of the raw material and per hour can be made small. The reduction in the amount of the feed of the diluent can save energy.
