The stability of bifunctional mixed catalyst for dimethyl ether synthesis from synthesis gas in slurry reactor was investigated.

The slurry reactor with inert liquid can transfer heat in time and avoid the catalysts sintering, CO rich synthesis gas can be used in this reactor.

Based on the fundamental data of kinetics, the one dimensional mathemtical mode l for the three phase slurry reactor of 30 000t/a dimethyl ether in the typical i ndustrial instance has been established by taking hydrogenation of CO,CO 2 and dehydration of methanol as independent reaction, and CO and CO 2 as key compone nts.
