Process for the conversion of a gasoline to a C6 to C8 aromatic compound and an olefin |
摘要 |
A catalyst composition and a process for converting a hydrocarbon stream such as, for example, gasoline to olefins and C6 to C8 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 C6 to C8 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.
