Title:
METHOD OF REGULATING TEMPERATURE IN REACTION VESSEL, REACTOR, AND PROCESS FOR PRODUCING DIMETHYL ETHER
Document Type and Number:
WIPO Patent Application WO/2009/078490
Kind Code:
A1
Abstract:
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.
