Abstract
研究了铜基催化剂上CO2加氢合成甲醇反应中掺人CO的作用，结果表明，在原料中添加少量CO，甲醇的选择性提高38%，收率提高25%；TPD-MS和TPSR-MS结果表明，CO能抑制催化剂表面起逆水汽变换作用的活性位对CO2的吸附，从而提高了CO2加氢合成甲醇的选抒性。
The effect of adding CO to the raw gases for methanol synthesis from the hydrogenation of carbon dioxide over the CuO/ZnO/Al2O3 catalysts has been reported. Small amount of CO in the raw gases can increase the selectivity and yield of methanol by 38% and 25%, respectively. TPD-MS and TPSR-MS results indicate that CO can suppress the adsorption of CO2 on the sites, which bring about the reverse water-gas shift reaction and hence promote the selectivity of methanol.
