| Abstract: | A highly active and selective Cu-ZnO-Al2o3 catalyst （denoted as RK-11） was pre- pared for hydrogenation of CO2 to afford methanol, and the catalytic performance of as-pre- pared RK-11 catalyst was evaluated. Results show that, when raw material gas consists of 68.5% H2, 2.0% CO, 20.5% CO2, and 9.0% N2, while temperature, gas hourly space veloc- ity, and pressure are 240 ℃, GHSV ： 6 000 h 1 , and 8.0 MPa, respectively, the conversion rate of CO2 and CO is as much as 35.2% and 39.8%. Relevant yield of methanol is as much as 686.1 g/（L · h）, and the selectivity of methanol product is as much as 99.3%. |
