摘要: A process for preparing C2 to C4 olefins includes introducing a feed stream of hydrogen gas and a carbon-containing gas into a reaction zone of a reactor and converting the feed stream into a product stream including C2 to C4 olefins in the reaction zone in the presence of a hybrid catalyst and in a non-oxidative atmosphere. The hybrid catalyst includes a metal oxide catalyst component comprising gallium oxide and zirconia, and a microporous catalyst component having an 8 membered ring structure. The process also includes periodically introducing an oxidative atmosphere into the reaction zone.

摘要: 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.

摘要: A method for preparing C2 to C5 paraffins includes introducing a feed stream including hydrogen gas and a carbon-containing gas selected from carbon monoxide, carbon dioxide, and mixtures thereof into a reaction zone of a reactor. Converting the feed stream into a product stream including C2 to C5 paraffins in the presence of a hybrid catalyst. The hybrid catalyst includes a microporous catalyst component; and a metal oxide catalyst component selected from (A) a bulk material consisting of gallium oxide, (B) gallium oxide present on a titanium dioxide support material, and (C) a mixture of gallium oxide and at least one promoter present on a support material selected from Group 4 of the IUPAC periodic table of elements.

摘要: Embodiments of the present disclosure are directed to methods of producing a hydrogen- selective oxygen carrier material comprising combining one or more core material precursors and one or more shell material precursors to from a precursor mixture and heat-treating the precursor mixture at a treatment temperature to form the hydrogen-selective oxygen carrier material. The treatment temperature is greater than or equal to 100° C. less than the melting point of a shell material, and the hydrogen- selective oxygen carrier material comprises a core comprising a core material and a shell comprising the shell material. The shell material may be in direct contact with at least a majority of an outer surface of the core material.
