合成甲醇反应是CO+H_2反应系列中较简单的反应之一,它与同系列的甲烷化反应有着不同的反应条件.从热力学观点来看,甲烷化反应和合成甲醇反应同是体积缩小反应,加压应该有利于两反应的进行,实际上合成甲醇反应需加压,而甲烷化反应却不一定需要加压.最近我们用动态分析技术对烃的临氢转化、乙炔加氢和苯加氢反应研究发现,在实际反应条件下,反应物在催化剂表面上的吸附可分为可逆与不可逆吸附两类,它们在多相催化反应中对活性、选择性和稳定性均有影响,但是它们对操作压力的依赖程度是不一样的.因此研究 The synthesis of methanol is one of the simpler reactions in the CO + H 2 reaction series, which has different reaction conditions with the same series of methanation reactions. From the thermodynamic point of view, the methanation reaction and the methanol synthesis reaction are the same as the volume reduction reaction, Pressurization should be conducive to the two reactions, in fact, the synthesis of methanol reaction needs to be pressurized, but the methanation reaction does not necessarily need to pressurize.We recently used dynamic analysis of hydrocarbon hydroconversion, acetylene hydrogenation and benzene hydrogenation The reaction study found that under the actual reaction conditions, the adsorption of reactants on the catalyst surface can be divided into two types: reversible and irreversible adsorption. They have influence on the activity, selectivity and stability in heterogeneous catalysis, The dependence on operating pressure is not the same, so research
