PREPARATION OF IMPROVED CATALYST FOR DEHYDROGENATION AND/OR DEHYDROCYCLIZATION OF HYDROCARBONS

摘要

A method for improving the activity of a dehydrogenation and dehydrocyclization catalyst composition and a process for improving the conversion and selectivity of paraffin hydrocarbons to olefin and aromatic compounds. The novel processes comprise adding calcium aluminate to a catalyst composition comprising a zinc aluminate support and a catalyst metal, and optionally a promoter metal.
