摘要
Abstract
CuO-ZnO-Al2O3 was prepared by gel-network co-precipitation for synthesizing dimethyl ether from carbon dioxide by hydrogenation and the effects of La, Ce, Co and Zr promoters on catalyst performance were investigated. The results showed that after adding a small amount of Ce, the selectivity of dimethyl ether reached 61.5% and the conversion rate of CO2 reached 40%.The physical-chemical propertise and catalytic performance of the catalysts were characterization by using BET, XRD, SEM, TPR and H2-TPD techniques.关键词
