Abstract: Certain amount of CO2 in syngas can significantly improve the reaction rate of methanol synthesis over Cu based catalysts, while the underline mechanism is still in controversial. This paper reviewed the research progress in the effect of CO2 in methanol synthesis from syngas, including the active centers, the intermediates, and the carbon source. The addition of the CO2 in the feed gas leads to a more complicated mechanism. Finally, the future research direction was briefly discussed to improve the efficiency of the methanol synthesis. We proposed that the fundamental research needs to narrow the differences with the industrial reactions especially in reaction conditions. And we should combine the in situ characterization techniques and theoretical calculations of the catalysts and reaction.

Key words: catalysis, syngas, carbon dioxide, methanol synthesis, hydrogenation

摘要: 在合成气(CO/H2)制备甲醇的过程中,向原料气中添加一定量CO2,可以大幅提高铜基催化剂上甲醇合成的反应速率,而对于这一现象的原因尚未有统一的认识。本文对合成气(CO/H2)制甲醇的过程中所添加的CO2对催化剂活性中心的影响、对合成过程中所出现的中间产物的影响,以及对合成甲醇的碳源的归属的影响等方面的研究进行了总结,可以看出,CO2的加入使得整个反应机理更加复杂。最后在此基础上对未来的研究方向进行了展望,认为相关基础研究应努力缩小和实际工业反应在条件上的差别,并把针对催化剂、反应过程的原位表征技术和理论计算相结合,以期为提高合成气制甲醇的效率提供借鉴。
