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.

Abstract:
Method and apparatus are described whereby a caustic-treated hydrocarbon feed mixture having a contaminating concentration of water and sulfur compounds is treated by separating the hydrocarbon feed into a first stream and a second stream. The first stream is contacted with an adsorbent material to produce a reactor feed stream having a significant reduction in the concentration of the contaminating water and sulfur compounds. The reactor feed stream is thereafter contacted in the presence of hydrogen under suitable isomerization conditions with an isomerization catalyst to produce an isomerate product.
