Abstract: Three kinds of ternary Cu-based catalysts ingcluding CuO-ZnO-ZrO2,CuO-ZnO-Al2O3 and CuO-ZnO-MgO are prepared by concurrent co-precipitation method,and their catalytic tests are carried out in a fixed-bed continuous flow micro-reactor.The activity evaluation results of these catalysts are compared,and these catalysts are characterized by XRD,H2-TPR,CO2-TPD and N2O titration.The results show that ZrO2 can give the catalyst higher activity than Al2O3 and MgO.CuO-ZnO-ZrO2 exhibits high catalytic activity at 250℃,3 MPa.The selectivity and yield of methanol over CuO-ZnO-ZrO2 are 56% and 58% respectively higher than that over CuO-ZnO-MgO,and 31% and 12% respectively higher than that over CuO-ZnO-Al2O3.
