| Abstract: | Impregnated catalyst preparation method,coal-based activated carbon carrier,different concentrations of HCl,HNO3 pretreatment conditions on the gas-phase oxidation of methanol carbonylation synthesis of dimethyl carbonate catalytic activity.The results show that：step-step impregnation method is superior;AC in the selected carrier in order to Benson AC3 as the carrier prepared CuCl / AC catalyst effect of the best,methanol conversion was 22.5%,DMC selectivity was 92.3%,DMC space-time yield of 131.2 g·kg-1·h-1;6 mol / L HCl pre-treatment the best,methanol conversion was 24.1%,DMC selectivity was 94.7%,DMC space-time yield of 147.2 g·kg-1·h-1. |
