摘　　要：CO加氢合成乙醇是当前C1化学研究的一个热点,但副产物甲烷的大量生成严重影响乙醇的选择性。本文从生成机理、热力学和动力学方面对乙醇和甲烷的生成加以分析,并对铑基催化剂上抑制甲烷促进乙醇合成的途径进行探讨,以期获得高选择性的乙醇。Synthesis of ethanol by hydrogenation of CO currently is a hot topic of research in C, chemistry, however, the formation of a large amount of byproduct methane seriously affects the selectivity of ethanol The formation mechanism, thermodynamics and kinetics of hydrogenation of CO to ethanol were analyzed and the pathways for promoting ethanol synthesis by inhibiting formation of methane over the Rh-based catalysts were discussed for the aim of enhancing the selectivity of ethanol in this reaction.
