苯在稀土钙钛矿型催化剂上完全氧化动力学

The Kinetics of Exhaustive Oxidation for Benzene over Rare-Earth Perovskite Structure Catalyst

应用气相色谱法,采用微型微分反应器研究了苯在稀土钙钛矿型催化剂上完全氧化的机理,为制造新型、高效催化剂提供参考性意见。实验结果表明,苯在稀土钙钛矿型催化剂上完全氧化反应的反应级数为1级,其Redox机理的活化能E_1=72.90 kJ/mol;E_2=136.93 kJ/mol。

The Redox mechanism equations of the kinetics of exhaustive oxidation for benzene over the rare-earth perovskite structure catalyst were studied. The parameters in equations were estimated by the least square method. The reaction order of the Redox mechanism equation was discussed.
