采用ＣＤＳ８１０实验系统，在实验条件为：常压、氢苯比３、温度３６３．１５～４５３．１５Ｋ时， 研究了在Ｎｉ／Ａｌ２Ｏ３催化剂上气相苯加氢反应的本征动力学．利用实验数据对几种可能的动 力学模型进行参数估值，最后得到该反应的动力学模型为：在Ｎｉ／Ａ１２Ｏ３催化剂上有两类吸 附中心，分别吸附氢、苯及其产物，且所有吸附达平衡；氢呈分子吸附；往苯环上加第一 个氢分子为速率控制步骤．该模型方程与实验数据拟合很好。平均偏差为５．４０％．
Using CDS810 experimental system, the intrinsic kinetics of the hydrogenation of benzene in the gas phase over Ni / Al2O3 catalyst was studied under the conditions of atmospheric pressure, hydrogen-benzene ratio of 3 and temperature of 363.15 ~ 453.15K. The experimental data were used to estimate the parameters of several possible kinetic models. The kinetic model of the reaction was obtained as follows: There are two types of adsorption centers on the Ni / A12O3 catalyst, which respectively adsorb hydrogen, benzene and their products, and all the adsorption Up to equilibrium; hydrogen is molecular adsorption; benzene ring to add the first hydrogen molecules for the rate control step. The model equation fits well with the experimental data. The average deviation is 5.40%.
