The effects of catalyst reduction temperature and reaction conditions on the reaction of CO 2 hydrogenation to dimethyl ether were investigated. The following results were obtained:① Catalyst reduction temperature has no evident effect on the reaction, the suitable reduction temperature ranges from 240℃-270℃; ② With increasing reaction temperature, CO 2 conversion and CO selectivity increase, but DME selectivity decreases. Above 240℃, CO 2 conversion decreases with increasing reaction temperature. ③ Increasing pressure and decreasing GHSV are benificial to the reaction of CO 2 hydrogenation to DME, with increases of CO 2 conversion and DME selectivity and decrease of selectivity to byproduct CO.
