研究了乙苯在不同硅铝比的HZSM-5和Hβ沸石上的歧化反应规律。硅铝比高的HZSM-5对间二乙苯的选择性和反应稳定性较好。沸石的表面酸量和孔径是控制选择性和稳定性的两个重要因素。
The disproportionation reaction of ethylbenzene on HZSM-5 and Hβ zeolites with different Si / Al ratios was studied. The selectivity and reaction stability of HZSM-5 with high Si / Al ratio to diethylbenzene is better. Zeolite surface acidity and pore size are two important factors that control selectivity and stability.
