    摘要： Catalytic combinations of refractory oxides and molybdenum and/or tungsten useful for hydrocarbon conversion and having modified porosity, permeability and/or surface characteristics are prepared by oxidizing a particle-form combination of a refractory oxide, a combustible support modifier and a Group VI-B metal compound in which less than 20 percent of the metal is hexavalent, by heating the particle-form combination in an oxidizing atmosphere at a temperature sufficient to convert the modifier to volatile oxidation products and remove it from the structure.

    摘要： Double bond isomerization of olefins utilizing a catalyst comprising nickel and sulfur on a porous carrier; the catalyst being prepared by forming an initial composite of the nickel with the carrier material, sulfiding the initial composite to provide a sulfur/nickel atomic ratio of at least about 0.9 in the sulfided composite, and then stripping sufficient sulfur from the sulfided composite with hydrogen to provide a final isomerization catalyst composition having a sulfur/nickel atomic ratio of less than about 0.9 and more than about 0.55.
