摘　　要：在等温积分反应器中,采用GS脱氢催化剂,研究了二乙苯脱氢反应宏观动力学。建立了二乙苯脱氢反应网络,根据不同反应机理,提出了4种二乙苯脱氢反应模型:L-H模型、Carra模型、经验模型、幂函数模型。通过模型筛选和统计学检验结果表明:L-H模型中各关键组分的ρ^(2)均大于0.9,F检验值大于10倍F_(0.05),最终确定L-H模型为二乙苯脱氢反应最佳动力学模型。In the isothermal integrating reactor,the GS dehydrogenation catalyst was used to study the macro-kinetics of the dehydrogenation reaction of diethylbenzene.A network for the dehydrogenation of diethylbenzene was established.According to different reaction mechanisms,four models dehydrogenationwere proposed:L-H model,Carra model,empirical model,and power function model.Through model screening and statistical testing,the results show that:The ρ^(2) of each key component in the L-H model is greater than 0.9,and the F test value is greater than 10 times F_(0.05).The L-H model is finally determined the best kinetic model for the dehydrogenation of diethylbenzene.
