| Abstract: | A series of Cu-ZnO-ZrO_2/HZSM-5 and promoted Cu-ZnO-ZrO_2/HZSM-5 catalysts prepared by a "coprecipitating sedimentation"Inethod exhibit high catalytic activities for the hydrogellation of carbonoxides and high selectivities tbr dimethyl ether. Among them, Mg-(Cu-ZnO-ZrO2)/V-HZSM-5 has the best catalytic activity: the conversion of CO is91.4%, the selectivity to dimethyl ether is 84.6%. In addition, Cu-ZnO-ZrO_2/HZSM-5 catalyst has excellent pertbrmances for CO_2 hydrogenation todimethyl ethers the conversion of CO_2 is 35%, the selectivity to dimethylether is 60.1%. |
