摘要
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 of ethylbenzene on HZSM-5 zeolites containing various silica to alumina ratio and Hβ zeolite were studied. Thy results indicated that the HZSM-5 with high silica to alumina ratio exhibit better selectivity of m-diethylbenzene and reaction stability. Thy catalysts selectivity and reaction stability were mainly dependent upon the sur face acidic amount and hole diameter of zeolites.
