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 and a promoter. The process for producing the composition comprises the steps: (1) combining a zeolite with a promoter under a condition sufficient to incorporate the zeolite with the promoter to produce a first promoted zeolite; (2) incorporating the first promoted zeolite with a second promoter to produce a second promoted zeolite; and (3) heating the second promoted 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.
