Abstract
Previously hydroformed feedstocks are upgraded to improve their octane rating by contacting said feedstocks in the presence of hydrogen with a sulfactivated catalyst comprising a metallic hydrogenation component, such as a platinum group metal, in combination with a crystalline aluminosilicate zeolite having uniform pore openings of about 5 Angstrom units. In its more specific aspects, the catalyst further contains a Group II-B metal such as zinc.
