Catalytic activity of natural zeolites in the conversion of methanol to dimethyl ether

The use of modified forms of zeolite-containing rocks (ZCRs) that comprise a mixture of zeolites as catalysts for the dehydration of methanol to dimethyl ether has been studied. Results of examination of the effect of chemical modification on the activity and stability of the catalysts have been described. It has been shown that modified rocks containing mordenite and clinoptilolite can be in principle used as methanol conversion catalysts. The contribution of each of the zeolite components to the catalyst performance has been determined.
