甲烷化反应在热力学方面已有系统的研究及完整的数据。关于 CO 甲烷化反应的动力学研究也已有广泛的报道,但对 CO_2(特别是 CO 存在时)甲烷化反应动力学的研究,相对地说来则较少。至于在镍催化剂上甲烷化反应的机理,直到现在仍然是一个有争议的问题。南化公司及南化公司研究院试生产的“J_(101)”、“J_(104)”及“77-65”等催化剂,均有很好的甲烷化工业价值,但系统的动力学 Methanation reaction has been systematically studied in thermodynamics and complete data. Kinetic studies on the methanation of CO have also been reported extensively, but relatively few studies on the kinetics of methanation of CO 2, especially in the presence of CO, have been reported. As for the mechanism of methanation on nickel catalysts, until now is still a controversial issue. Catalysts such as “J_ (101)”, “J_ (104)” and “77-65” pilot-produced by the research institute of Nanhua Chemical Company and Nanhua Chemical Company all have good methanation industrial value, but the systematic kinetics
