摘要： A dual function composite catalyst for isomerizing an isomerization feed containing an aromatic C.sub.8 mixture of ethyl benzene and xylene, comprises (a) a crystalline aluminosilicate zeolite having a low acid activity as measured by an alpha value of from 0.02 to 11, an average crystal size of not more than 0.4 microns for at least 50% by weight of the crystals, a silica to alumina ratio of at least about 12, a constraint index of about 1 to 12, a xylene sorption capacity greater than 1 gram per 100 grams of zeolite, and an ortho-xylene sorption time for 30 percent of said capacity less than 10 minutes, said sorption capacity and sorption time being measured at 120.degree. C. and a xylene pressure of 4.5.+-.0.8 mm of mercury, and (b) a supported metal of Group VIII of the Periodic Table having a high hydrogenation/dehydrogenation activity to provide the catalyst with a dehydrogenation activity of at least 10. The catalyst has an alpha value of 0.005 to 3.
摘要翻译：用于异构化异构化进料的双功能复合催化剂，其含有乙苯和二甲苯的芳族C 8混合物，包括（a）具有低酸活性的结晶硅铝酸盐沸石，其α值为0.02至11，平均晶体尺寸对于至少50重量％的晶体，二氧化硅与氧化铝的比例至少约为12，约1到12的约束指数，每100克沸石的二甲苯吸附容量大于1克，不超过0.4微米，并且邻二甲苯吸附时间为所述容量的30％小于10分钟，所述吸附容量和吸附时间在120℃下测量，二甲苯压力为4.5 +/- 0.8mm汞柱，（b）元素周期表第VIII族的负载金属具有高的氢化/脱氢活性，以使催化剂具有至少10的脱氢活性。该催化剂具有0.005至3的α值。
