Abstract
A reforming process is disclosed wherein a hydrocarbon feed is contacted with two reforming catalysts at conditions which favor reforming. The first reforming catalyst comprises a metallic oxide support having disposed therein a Group VIII metal. This first reforming catalyst may contain Group VIII metal promoters, such as rhenium, tin, germanium, cobalt, nickel, iridium, rhodium, ruthenium and combinations thereof. The second reforming catalyst is a non-acidic catalyst comprising a large-pore zeolite containing at least one Group VIII metal. A preferred first reforming catalyst comprises alumina having disposed therein in intimate admixture platinum and rhenium. A preferred second reforming catalyst is a non-acidic catalyst comprising a type L zeolite containing platinum.
