Method of regulating temperature in reaction vessel, reactor, and process for producing dimethyl ether

摘要

The method aims to improve the controllability of temperature and conversion in a reaction vessel in synthesizing, e.g., dimethyl ether from methanol through equilibrium reactions accompanied by an endothermic reaction. Catalyst layers are disposed in a reaction vessel, and a quench zone for cooling a mixture comprising methanol and dimethyl ether is formed between the catalyst layers. A fluid comprising at least either of dimethyl ether and the water which has generated together with the dimethyl ether is supplied as a quench fluid to the quench zone.
