Abstract: Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed in which the hydrocarbon reactant and a supported transition metal catalyst—containing molybdenum, tungsten, or vanadium—are irradiated with a light beam at a wavelength in the UV-visible spectrum, optionally in an oxidizing atmosphere, to form a reduced transition metal catalyst, followed by hydrolyzing the reduced transition metal catalyst to form a reaction product containing the alcohol compound and/or the carbonyl compound.

Abstract: Techniques are provided for catalyst preparation. A method includes heating a mixture of one or more transition metal compounds and an oxide support or a chromium containing oxide support to a temperature or a set of temperatures that enables the a transition metal compound of the one or more transition metal compounds to sublime, melt, or thermally decompose, such that a transition metal of the one or more transition metal compounds reacts with and is deposited onto a surface of the oxide support or the chromium containing oxide support to form a catalyst, and activating the catalyst. The catalyst is configured to facilitate a reaction that produces a target inorganic material.

Abstract: Methods for modifying a catalyst system component are disclosed in which a feed mixture containing a fluid and from 1 to 15 wt. % of a catalyst system component is introduced into an inlet of a hydrocyclone, an overflow stream containing from 0.1 to 5 wt. % solids and an underflow stream containing from 10 to 40 wt. % solids are discharged from the hydrocyclone, and the underflow stream is spray dried to form a modified catalyst component. Often, from 4 to 20 wt. % of the catalyst system component in the feed mixture has a particle size of less than or equal to 20 μm, or less than or equal to 10 μm.

Abstract: Processes for cracking an alkane reactant to form a lower aliphatic hydrocarbon product and for converting an alkane reactant into a higher aliphatic hydrocarbon product are disclosed, and these processes include a step of contacting the alkane reactant with a supported chromium (II) catalyst. In addition to the formation of various aliphatic hydrocarbons, such as linear alkanes, branched alkanes, 1-alkenes, and internal alkenes, aromatic hydrocarbons and hydrogen also can be produced.

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: Methods for making a supported chromium catalyst are disclosed, and can comprise contacting a silica-coated alumina containing at least 30 wt. % silica with a chromium-containing compound in a liquid, drying, and calcining in an oxidizing atmosphere at a peak temperature of at least 650° C. to form the supported chromium catalyst. The supported chromium catalyst can contain from 0.01 to 20 wt. % chromium, and typically can have a pore volume from 0.5 to 2 mL/g and a BET surface area from 275 to 550 m2/g. The supported chromium catalyst subsequently can be used to polymerize olefins to produce, for example, ethylene-based homopolymers and copolymers having high molecular weights and broad molecular weight distributions.
