摘　　要：利用加压微反装置在Ｐｄ／Ａｌ２Ｏ３催化剂上研究了邻二氯苯加氢脱氯动力学。按照ＣｌＣｌ→Ｃｌ→串联脱氯步骤，从非均相催化反应的Ｌ－Ｈ机理、Ｒｉｄｅ－ａｌ机理以及经验规律出发，对该连串反应提出了多个动力学模型，通过对实验数据的拟合和模型筛选，建立了该反应的机理模型和经验模型动力学方程，根据得到的反应模型对反应进行讨论。The reaction kinetics of hydrodechlorination of o dichlorobenzene on a Pd/Al 2O 3 catalyst has been studied by using a pressure microreactor device. Based on the following consecutive reaction scheme Cl Cl Cl 17 kinds of kinetic models have been proposed from the L H mechanism and Rideal mechanism of hoterogeous catalytic reaction as well as experientical law. By fitting the experimental data and trying and selecting the models, the kinetic equations of mechanism model and experiential model were put forword. From the models obtained, the reaction was dicussed.
