Abstract
A cooled reactor for the production of dimethyl ether by catalytic dehydration of methanol in the gas phase, the reactor having 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. The conversion of methanol to dimethyl ether is increased and the formation of undesired by-products is decreased.
