DEHYDRATION OF METHANOL INTO DIMETHYL ETHER USING CATALYSTS CONTAINING A ZEOLITHE ON A SILICON CARBIDE SUBSTRATE

摘要

The present invention relates to a method for preparing dimethyl ether by the catalytic dehydration of methanol, that comprises using a catalyst containing a zeolithe immobilised on a silicon carbide substrate, e.g. a zeolithe of the ZSM-5 type on silicon carbide extrudates or on a silicon carbide cellular foam.
