Abstract
The effect of adding CO to the raw-gases for methanol synthesis from t he hydrogenation of carbon dioxide over the CuO/ZnO/Al2O3 catalysts ha s 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 C O2 on the sites, which bring about the reverse water-gas shift reactio n and hence promote the selectivity of methanol.
