  • Solid superacid catalysts comprising platinum metal
    Patent number: 5629257
    Abstract: A sulfated solid catalyst is provided which comprises (1) oxide or hydroxide of Group III or Group IV element, e.g. zirconium, and (2) a first metal comprising a metal or combination of metals selected from the group consisting of platinum, palladium, nickel, platinum and rhenium, and platinum and tin. The catalyst may further comprise (3) a second metal selected from the group consisting of Group VIII elements, e.g. iron. One embodiment of the invention further comprises (4) a third metal selected from the group consisting of Group V, VI and VII elements, e.g. manganese. The catalyst of the invention is useful for the isomerization of normal alkanes having 4 to 40 carbon atoms per molecule, for the naphtha upgrading of a hydrocarbon feedstock and for the hydrocracking of a hydrocarbon feedstock.

  • Dehydrogenation processes using catalysts comprising catalytic metal on a nonacidic support
    Patent number: 5489722
    Abstract: Organic compounds are dehydrogenated by contact with a catalyst prepared by oxidizing and then sulfiding a composition comprising Group VIIIA (first or second row) catalytic metal on a nonacidic porous support, for example alumina, to produce compositions which have good dispersion of a catalytically active metal component and of sulfide species over the surface of the compositions and high activity as catalysts for the dehydrogenation of organic compounds. In one embodiment of the invention the catalyst used in the process of the invention has ratios of nickel, and/or sulfide species to peak areas of aluminum in the support, as determined by X-ray photoelectron spectroscopy (XPS), which improve their activity and stability for use as dehydrogenation catalysts.

  • Compositions comprising sulfided nickel and alumina useful as dehydrogenation catalysts
    Patent number: 5468710
    Abstract: Compositions of matter comprising sulfided nickel and nonacidic alumina, and having certain ratios of specific peak areas for nickel, for aluminum, for sulfide ion and/or for cesium, as determined by X-ray photoelectron spectroscopy, are useful as catalysts for dehydrogenation of organic compounds, and are superior as such catalysts to otherwise similar compositions not having such ratios.

  • Process of making dehydrogenation catalysts by oxidizing and sulfiding catalytic metal on a nonacidic support
    Patent number: 5462904
    Abstract: The process of the invention comprises oxidizing and then sulfiding materials comprising Group VIA or Group VIIIA (first or second row) catalytic metal on a nonacidic porous support, to produce compositions which have good dispersion of a catalytically active metal component and of sulfide species over the surface of the compositions and high activity as catalysts for the dehydrogenation of organic compounds.
