| 摘 要： | 研究了CO2在Cu－Zn－Al催化剂上的加氢合成甲醇反应。发现在原料气中添加少量的CO可提高甲醇的选择性和收率。TPD和TPSR结果表明，CO占据催化剂表面部分活性位并抑制CO2的逆水煤气转换，促进了甲醇的生成。

| Abstract: | Methanol synthesis from CO2 hydrogenation over Cu-Zn-Al catalysts was studied. The addition of a small amount of CO in the feed resulted in the increase of methanol selectivity and yield. The results of TPD and TPSR indicated that CO occupied the active sites, thus suppressed the reverse water-gas reaction of CO2 and enhanced the formation of methanol. |
