Hydrocarbon conversion catalyst composition and processes therefor and therewith

摘要

A catalyst composition and a process for producing the catalyst composition for use in a hydrocarbon conversion process are disclosed. The composition comprises an inorganic support and a Group VIII metal. The process comprises: (1) combining at least one Group VIII metal compound and an inorganic support to form a mixture, (2) calcining the mixture under a condition sufficient to convert the metal compound to its oxide form to produce a heated mixture, (3) contacting the heated mixture with a boron compound under a condition sufficient to reduce the oxidation state of the metal whereby a boron-treated composition is produced; and (4) contacting the boron-treated composition with a compound comprising aluminum and halogen.
