COOLED REACTOR FOR THE PRODUCTION OF DIMETHYL ETHER FROM METHANOL

摘要

There is proposed a cooled reactor for the production of dimethyl ether by catalytic dehydration of methanol in the gas phase, which comprises an adiabatic catalyst bed as starting zone, a moderator zone cooled by direct or indirect heat exchange, and optionally an adiabatic catalyst bed as conditioning zone. By using the reactor according to the invention, the conversion of methanol to dimethyl ether can be increased and the formation of undesired by-products can be decreased.
