Hydrocarbon conversion catalyst composition and processes therefor and therewith

摘要

A catalyst composition, a process for producing the composition, and a hydrocarbon conversion process for converting a hydrocarbon stream such as, for example, gasoline, to olefins and C6 to C8 aromatic hydrocarbons such as benzene, toluene and xylenes are disclosed. The catalyst composition comprises a zeolite and phosphorus. The process for producing the composition comprises the steps of: (1) combining a zeolite with a phosphorus compound under a condition sufficient to produce a phosphorus-promoted zeolite; and (2) heating the phosphorus-promoted zeolite. The hydrocarbon conversion process comprises contacting a hydrocarbon stream with the catalyst composition under a condition sufficient to effect the conversion of a saturated hydrocarbon to an olefin and a C6 to C8 aromatic hydrocarbon.
