以 C10芳烃中的主要组分四甲苯和二乙苯为模型化合物，用脉冲反应器研究其在纳米 ZSM-5分子筛催化剂上的轻质化反应。结果表明：在纳米 ZSM-5上，低温时均四甲苯主要进行异构反应，高温时则发生脱烷基反应和烷基转移反应，反应空速对该反应的竞争影响较大；二乙苯主要进行脱烷基反应；若以 BTX（苯、甲苯、二甲苯）的生成量最大为目标，则这两类反应物均宜在低温和高催化剂用量的条件下进行反应，这也可作为工业 C10混合芳烃轻质化的最佳反应条件。

The conversions of tetramethylbenzene and diethylbenzene,the main components in C10 fraction,to light aromatics on nano-ZSM-5 were studied in a pulse micro-reactor. The results show that at low temperature,isomerization of tetramethylbenzene is the main reaction,while at high tempera-ture,the reaction is changed to dealkylation and transalkylation. The space velocity affects the competi-tion of the two kinds of reactions of tetramethylbenzene. As to diethylbenzene,the dealkylation is the main reaction. If the maximum amount of BTX is the reaction goal,low space velocity and low tempera-ture are the optimum reaction conditions for both of the reactants. The optimum reaction conditions can be used for lightening the C10 aromatics fraction in industrial unit.
