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.
La présente invention concerne un procédé de préparation de diméthyl éther par déshydratation catalytique du méthanol, dans lequel on emploie un catalyseur à base d'une zéolithe immobilisée sur un support de carbure de silicium, par exemple une zéolithe de type ZSM-5 supportée sur des extrudés de carbure de silicium ou sur une mousse alvéolaire de carbure de silicium.
