    摘要： A catalyst composition and a process for converting a hydrocarbon stream such as, for example, gasoline to olefins and C.sub.6 to C.sub.8 aromatic hydrocarbons such as toluene and xylenes are disclosed. The catalyst composition comprises an alumina and a silica wherein the weight ratio of aluminum to silicon is in the range of from about 0.002:1 to about 0.25:1. The process comprises contacting a hydrocarbon stream with the catalyst composition under a condition sufficient to effect the conversion of a hydrocarbon to an olefin and a C.sub.6 to C.sub.8 aromatic hydrocarbon. Also disclosed is a process for producing the catalyst composition which comprises: (1) contacting a zeolite with an effective amount of a base under a condition sufficient to effect a reduction in silicon content of said zeolite to produce a base-leached zeolite; and (2) contacting said base-leached zeolite with an effective amount of an acid under a condition sufficient to effect a reduction in aluminum content of said base-leached zeolite.

    摘要： A catalyst composition and process for preparing such catalyst composition which can be useful in contacting a hydrocarbon-containing fluid which contains a highly unsaturated hydrocarbon such as 1,3-butadiene, in the presence of hydrogen, with such catalyst composition in a hydrogenation zone under a hydrogenation condition effective to hydrogenate such highly unsaturated hydrocarbon to a less unsaturated hydrocarbon such as n-butene is disclosed. Such process for preparing a catalyst composition includes (1) combining a zeolite, a Group VIB metal, and an inorganic support to form a modified zeolite; (2) calcining such modified zeolite under a calcining condition to produce a calcined, modified zeolite; and (3) contacting such calcined, modified zeolite with a carburizing agent under a carburizing condition to provide such catalyst composition.
