DEHYDRATION OF METHANOL TO DIMETHYL ETHER USING CATALYSTS BASED ON A ZEOLITE SUPPORTED ON SILICON CARBIDE

摘要

A process for the preparation of dimethyl ether by catalytic dehydration of methanol, in which there is used a catalyst based on a zeolite immobilized on a silicon carbide support, for example a zeolite of type ZSM-5 supported on silicon carbide extrudates or on a silicon carbide cellular foam.
