    摘要: Organic compounds, particularly hydrocarbons, are oxidatively dehydrogenated to more unsaturated compounds by contact, under reaction conditions, with air, steam and a calcined solid catalyst composition comprising titanium, at least one component selected from the group consisting of tungsten or molybdenum, and at least one component selected from the group consisting of phosphorus, bismuth, lead, antimony or arsenic. Representative of such oxidative dehydrogenation processes is the conversion of butane to butenes and butadienes.

    摘要: A novel cracking catalyst, a method of preparing same, and an improved hydrocarbon cracking process are provided wherein the adverse effects of metals such as nickel, vanadium, iron, copper, and cobalt on the cracking catalys are reduced by contacting the cracking catalyst with a sufficient amount of at least one indium modifier selected from the group consisting of elemental indium and indium compounds free of the element antimony.
