ABSTRACT:
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 a zeolite, a binder, and boron wherein the weight of boron is in the range of from about 0.01 to about 10 weight %. 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) combining a zeolite with a coke-reducing amount of a binder under a condition effective to produce a zeolite-binder mixture; (2) contacting said zeolite-binder mixture with coke-reducing amount of a boron compound under a condition effective to produce a boron-incorporated or -impregnated zeolite; and (3) calcining the boron-incorporated or -impregnated zeolite.
