ABSTRACT:
A catalyst composition, a process for producing the composition, and a hydrotreating 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 a zeolite, a clay, and a promoter. The process for producing the composition comprises the steps: (1) combining a zeolite with a clay and a promoter under a condition sufficient to bind the clay to the zeolite to produce a clay-bound zeolite; and (2) heating the clay-bound zeolite to produce a modified zeolite. The hydrotreating 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.
