摘要：依据甲苯歧化与C9芳烃烷基转移反应的实验结果对该复杂反应体系进行了简化处理。简化后的反应体系由甲苯歧化、甲苯与三甲苯烷基转移、甲乙苯加氢脱烷基 3个主反应和甲苯与甲乙苯烷基转移、乙苯加氢脱烷基和三甲苯歧化 3个副反应组成。经动力学参数估值确定了相应的动力学方程式 ;并从产物异构体的组成出发 ,讨论了 β沸石催化剂的择形性。
On the basis of tube reactor experimental data analysis, a simplified model of the complex reaction system of toluene disproportionation and C 9 aromatics transalkylation was obtained The simplified reaction model includes three main reactions, which are toluene disproportionation, transalkylation of toluene and trimethylbenzene and hydrodealkylation of methylethylbenzene, and three secondary reactions, which are trimethylbenzene disproportionation, transalkylation of toluene and methylethylbenzene and hydrodealkylation of ethylbenzene The corresponding kinetics equations of this reaction system were proposed through parameter estimation The experimental data and shape selectivity of β zeolite were discussed on the basis of isomer composition of reaction products
