为了改善气候条件并解决碳资源问题，需要开发能将CO2转化为有价值材料的技术。在所考虑的多种选项中，甲醇因其是重要化工原料并可作为石油补充替代合成燃料，因而通过加氢将CO2转化为甲醇的研究倍受关注。 CO2是最稳定的化合物之一。从CO2加氢制甲醇（CO2+3H2=CH3OH+H2O，G523K=46.5kJ/mol）较之从CO加氢制甲醇（CO+2H2=CH3OH，G523K=26.9kJ/mol）在热力学上不利得多。在工业上要求的反应温度（523K）下CO2加氢的平衡转化率相当低。因此，开发能在高原料气空速条件下操作的高效催化剂（以便实现高的单程甲醇时空产率），...Hydrogenation of carbon dioxide has been considered as one of the most economical and effective ways to chemically fix huge amount of emitted CO2. In order to improve climate conditions, it is desirable to develop methods to convert CO2 into valuable chemicals. Among the options considered, catalytic hydrogenation of CO2 to produce methanol has received much attention. Since carbon dioxide is on...学位：工学硕士院系专业：化学化工学院化学工程与生物工程系_工业催化学号：2062006115205
