  • Patent number: 4401558
    Abstract: There is disclosed a catalyst, which catalyst comprises a physical particle-form mixture of a Component A and a Component B, said Component A comprising one or more Group VIII noble metals and a combined halogen deposed on a refractory inorganic oxide and said Component B comprising a metal from Group IVB or Group VB of the Periodic Table of Elements and a combined halogen deposed on a refractory inorganic oxide. Such catalyst is suitable for use in a hydrocarbon conversion reaction zone.The catalyst can be employed in a process for the reforming of a hydrocarbon stream, which process comprises contacting said stream in a reaction zone under reforming conditions and in the presence of hydrogen with said catalyst. The catalyst is not presulfided. A preferred process comprises contacting a hydrocarbon stream that contains a substantial amount of sulfur.
