| Abstract: | As a new type of the silica mesoporous materials mesoporous carbon, has the broad prospect in the catalyst carrier application. Series of CuO-ZnO/PF of solid load catalyst were prepared by sol-gel method, and the catalyst applies to the synthesis of dimethyl carbonate （DMC） from methanol and carbon dioxide. The results of the study show that in the temperature about 320.5 C,with the intensity of pressure 3.0 MPa,and the n（CuO） ： n（ZnO）-2 ： 1,the catalyst,which is calcined at 650 C has the best catalysis performance. The conversional rate of methyl alcohol reaches 97.55% and the selective of dimethyl carbonate reaches 94.43%. |
| Keywords: | CuO-ZnO/PF methyl alcohol dimethyl carbonate catalytic activity meso-porous carbon |
