Abstract: A hydrocarbon compound and carbon monoxide are reacted in the presence of either a supported chromium (VI) catalyst or a supported chromium (II) catalyst, optionally with UV-visible light irradiation and/or exposure to an oxidizing atmosphere, followed by removing a reaction product containing an alcohol compound and/or a carbonyl compound from the respective chromium catalyst. Often, the reaction product contains one or more ketone and/or aldehyde compounds.

Abstract: Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed, and these processes include the steps of irradiating the hydrocarbon reactant and a supported chromium catalyst comprising chromium in a hexavalent oxidation state with a light beam at a wavelength in the UV-visible spectrum to reduce at least a portion of the supported chromium catalyst to form a reduced chromium catalyst, and hydrolyzing the reduced chromium catalyst to form a reaction product comprising the alcohol compound and/or the carbonyl compound. In addition, these processes can further comprise a step of calcining all or a portion of the reduced chromium catalyst to regenerate the supported chromium catalyst.

Abstract: The present invention relates to a catalyst composition comprising a gold nanoparticle superlattice embedded in hierarchical porous silica and a method for manufacturing the same. The catalyst composition comprising a gold nanoparticle superlattice embedded in hierarchical porous silica according to the present invention comprises micropores and mesopores in the superlattice, so that these pores are channelized to allow the rapid access of reactants to surfaces of gold nanoparticles, and the catalyst composition is very structurally stable and has excellent catalytic activity, and thus has an effect of exhibiting a CO conversion rate of 100% at room temperature.

Abstract: An oxide of sulfur oxygen transfer reagent is provided. A method of producing olefins from hydrocarbons with a concomitant production of water (oxidative dehydrogenation), using the oxide of sulfur oxygen transfer reagent is also provided. The sulfur oxygen transfer reagent can be used as an oxygen transfer reagent, and therefore acts as a non-metal carrier, for oxygen in a redox looping reactor for an oxidative dehydrogenation process such as the conversion of ethane to ethylene. The reduced forms of oxides of sulfur, formed in in this oxidative dehydrogenation process, can be re-oxidized with air and generate useful process heat. Also provided are methods of using the oxide of sulfur oxygen transfer reagent, and an apparatus for effecting the oxidative dehydrogenation of the hydrocarbon feed. Methods of producing the oxide of sulfur oxygen transfer reagent are also provided.

Abstract: A method of operating a polyethylene reactor system includes feeding ethylene, an optional first comonomer, a diluent, and a chromium-based catalyst to a first polymerization reactor. The method further includes contacting ethylene and the comonomer with the catalyst in the first polymerization reactor to form a first product including a first polyethylene. The method further includes feeding the first product from the first polymerization reactor to a second polymerization reactor. The method further includes contacting ethylene and a second optional comonomer with catalyst from the first reactor in the second polymerization reactor to form a second product including the first polyethylene and a second polyethylene. The method further includes controlling one or both of a molecular weight or a breadth of molecular weight distribution of the second product by adjusting a rate of hydrogen fed to one or both of the first polymerization reactor or the second polymerization reactor.
