  • Publication number: 20210317004
    Abstract: Embodiments of the present disclosure are directed to hydrogen-selective oxygen carrier materials and methods of using hydrogen-selective oxygen carrier materials. The hydrogen-selective oxygen carrier material may comprise a core material, which includes a redox-active transition metal oxide; a shell material, which includes one or more alkali transition metal oxides; and a support material. The shell material may be in direct contact with at least a majority of an outer surface of the core material. At least a portion of the core material may be in direct contact with the support material. The hydrogen-selective oxygen carrier material may be selective to combust hydrogen in an environment that includes hydrogen and hydrocarbons.

  • Publication number: 20210292259
    Abstract: According to one or more embodiments described herein, a method for dehydrogenating hydrocarbons may include passing a hydrocarbon feed comprising one or more alkanes or alkyl aromatics into a fluidized bed reactor, contacting the hydrocarbon feed with a dehydrogenation catalyst in the fluidized bed reactor to produce a dehydrogenated product and hydrogen, and contacting the hydrogen with an oxygen-rich oxygen carrier material in the fluidized bed reactor to combust the hydrogen and form an oxygen-diminished oxygen carrier material. In additional embodiments, a dual-purpose material may be utilized which has dehydrogenation catalyst and oxygen carrying functionality.

  • Patent number: 8697930
    Abstract: Convert a methylamine (e.g. monomethylamine, dimethylamine and trimethylamine) to a mixture of olefins (e.g. ethylene, propylene and butylene) by placing the methylamine, optionally in a mixture with at least one of ammonia and an inert diluent, in contact with a microporous acidic silicoaluminophosphate catalyst or a microporous aluminosilicate catalyst.

  • Patent number: 8674149
    Abstract: Oxidatively halogenate methane by placing a feedstream that comprises methane, a source of halogen, a source of oxygen and, optionally, a source of diluent gas in contact with a first catalyst (e.g. a solid super acid or a solid super base) that has greater selectivity to methyl halide and carbon monoxide than to methylene halide, trihalomethane or carbon tetrahalide. Improve overall selectivity to methyl halide by using a second catalyst that converts at least part of the feedstream to a mixture of methyl halide, methylene halide, trihalomethane, carbon tetrahalide and unreacted oxygen, and placing that mixture in contact with the first catalyst which converts at least a portion of the methylene halide, trihalomethane and carbon tetrahalide to carbon monoxide, hydrogen halide and water.

  • Publication number: 20080275279
    Abstract: An oxidative halogenation process involving contacting methane, a C1 halogenated hydrocarbon, or a mixture thereof with a source of halogen and a source of oxygen, at a molar ratio of reactant hydrocarbon to source of halogen in a feed to the reactor greater than 23/1, and/or at a molar ratio of reactant hydrocarbon to source of oxygen in a feed to the reactor greater than about 46/1; in the presence of a rare earth halide or rare earth oxyhalide catalyst, to produce a halogenated C1 product having at least one more halogen as compared with the C1 reactant hydrocarbon, preferably, methyl chloride. The process can be advantageously conducted to total conversion of source of halogen and source of oxygen. The process can be advantageously conducted with essentially no halogen in the feed to the reactor, by employing a separate catalyst halogenation step in a pulse, swing or circulating bed mode.

  • Publication number: 20030092921
    Abstract: A catalyst comprises a titanium-containing oxide and gold deposited by deposition-precipitation on the oxide in a gold-bearing solution where the solution and the oxide are centrifuged to separate out the catalyst. The catalyst is used in oxidation of an olefin by contacting the olefin with a reaction gas and the catalyst which is heated in the reaction gas to a reaction temperature at a controlled heating rate to avoid agglomeration of gold species.
