：Cu/zn/Al/Mn4组分催化剂对CO2加氢合成甲醇原料气中CO的助催化作用进行研究。结果表明，CO占据了部分催化剂表面起逆水汽变换反应的活性位，从而降低CO2转化率，但甲醇选择性和收率得到了提高。Au Chaktong (Chemistry Department, Hong Kong Baptist University, Kowloon Tong, Hong Kong) The eFFect of adding Co to the Feed gas as a promotor has been investigated For methanol synthesis via CO 2 hydrogenation over a Cu/Zn/Al/Mn catalyst. The results indicate that CO may capture a small amount of active sites on the catalyst surFace which bring about the reverse water gas shiFt reaction.Thus the conversion of CO 2 is suppressed, but the selectivity to and yield of methanol are improved
