Non-noble-metal-mordenite reforming catalyst

Abstract

Abstract The catalyst comprises a hydrogenation component comprising a member selected from the group consisting of a metal of Group VIA, compounds of a metal of Group VIA, and mixtures thereof supported on a co-catalytic solid support comprising mordenite and a porous refractory inorganic oxide. The hydrogenation component may be characterized further by a member selected from the group consisting of rhenium, compounds of rhenium, a non-noble metal of Group VIII, compounds of a non-noble metal of Group VIII, and mixtures thereof. The preferred Group VIA metal is molybdenum. The catalyst preparation may comprise blending finely-divided mordenite into a sol or gel of the refractory inorganic oxide to form a blend, gelling the blend, if a sol is present, to form a gel by adding a solution of a suitable inorganic ammonium-affording compound, and drying and calcining the gel to form a calcined material. According to the invention, the reforming process comprises contacting a petroleum hydrocarbon stream in a reforming zone under reforming conditions and in the presence of hydrogen with the above catalyst. In one embodiment, the process comprises contacting a partially-reformed hydrocarbon stream in a reforming zone under reforming conditions and in the presence of hydrogen with the above catalyst. In another embodiment, the process comprises contacting the petroleum hydrocarbon stream in a first reforming zone under reforming conditions and in the presence of hydrogen with a catalyst comprising a platinum group metal and a halide on alumina to produce a first reformate and subsequently contacting the first reformate in a second reforming zone under reforming conditions and in the presence of hydrogen with the above catalyst.
