摘要
采用工业上应用较成功的HC-402-2型镍基均相Ziegler型络合催化剂，在排除扩散影响的条件下，研究了苯均相催化加氧制环已烷的反应动力学。在反应温度150～210℃、总压1．0～24MPa的范围内，考察了反应温度、氢分压和苯浓度对反应速率的影响。实验结果表明，苯加氢均相催化反应对苯浓度的反应级数为零级，对氢分压的反应级数为一级，反成活化能为3643527J／mol。经检验，该动力学模型的相关系数大于0．9，模型合理，能够描述实际反应过程。
Reaction kinetics of benzene hydrogenation was studied with HC-402-2 commercial homogeneous Ziegler Ni-base complex catalyst. The experiments were carried out without diffusion effect. The effects of reaction temperature, hydrogen partial pressure and benzene concentration on reaction rate were investigated in ranges of 150 - 210℃ and 1. 0 - 2. 4 MPa （ total pressure ）. Hydrogenation is zero-order reaction with benzene concentration and first-order reaction with hydrogen partial pressure. The apparent activation energy is 36 435.27 J/mol. The correlation coefficient of kinetics model is more than 0.9.
