摘要
综述了影响甲苯甲基化择形催化的因素,讨论了沸石的内外表面酸中心及酸强度、沸石的孔道、反应物和产物的吸附等因素对提高对二甲苯选择性的影响。
The affecting factors in toluene methylation by shape selective catalysis were reviewed,and the effect of acid site on internal and external surface of zeolite and acid—strength,channel in zeolite,and adsorption of reactants and products etc.on enhancing the p-xylene selectivity was discussed.
