摘要：

A series of composite catalysts were prepared by the wet mixing method, and the mass ratio of CuO-ZnO-Al2O3-ZrO2 component to HZSM-5 zeolite (molar ratio of SiO2 to Al2O3 being 25) was 2:1. The CuO-ZnO-Al2O3-ZrO2 (CuO/ZnO/Al2O3=3/6/1 by weight) component was prepared by a modified 'two-step' co-precipitation method. The effects of ZrO2 on the performance of CuO-ZnO-Al2O3/HZSM-5 catalyst for dimethyl ether synthesis from CO2 hydrogenation were investigated. It was found that ZrO2 improved the properties of CuO-ZnO-Al2O3/HZSM-5 as a structural promoter.
