在工业上制造催化剂有机械混合法、浸渍法、熔融法和共沉淀法等工艺过程。用共沉淀法制造的催化剂,不但组分间混合均匀,高度分散,而且按催化反应中对催化剂的表面结构——比表面、孔容、孔径大小、分布等,较适应于宏观动力学过程的要求。上海化工学院曾对国产C_6、C_9、WB-1型三种一氧化碳中变催化剂的反应动力学进行过研究,按统一的动力学方程整理的三种催化剂正反应活化能E分别为:E_(C6)=27000[卡/克分子];E_(C9)=24000[卡/克分子];E_(WB-1)=21000[卡/克分子]。上述三种催化剂都系Fe_3O_4为活性组分,Cr_2O_3为助催化剂,特别是C_9和WB-1型无论是
In the industrial manufacture of catalysts are mechanical mixing, impregnation, melting and coprecipitation process. The coprecipitation catalyst produced by this method not only has uniform and highly dispersed components, but also adapts to the macroscopic kinetic process according to the surface structure of the catalyst - specific surface area, pore volume, pore size and distribution, etc. Claim. Shanghai Institute of Chemical Technology has studied the reaction kinetics of C_6, C_9 and WB-1 three kinds of carbon monoxide mid-shift catalysts. The activation energies E of the three catalysts sorted by unified kinetic equation are E_ (C6 ) = 27,000 [cal / mol]; E_ (C9) = 24,000 [cal / mol]; E WB-1 = 21,000 cal / mol. The above three catalysts are Fe_3O_4 as the active component, Cr_2O_3 as cocatalyst, especially C_9 and WB-1 type
