摘要： A continuous process for aerobic oxidation of methane. The process includes a reactor (10) comprising a bed of a metal-based catalyst (16), a methane feed stream (30) into the reactor (10), an oxygen feed stream (30) into the reactor (10), and a water feed stream (12) into the reactor (10). The methane is oxidised in a single step in the reactor (10) over the metal-based catalyst (16) in the presence of liquid water to produce a reaction product including compounds selected from formaldehyde, oligomers of formaldehyde, methanediol, and products of addition reactions between methanol and formaldehyde, and mixtures thereof.

摘要： Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed, and these processes include the steps of forming a supported chromium catalyst comprising chromium in a hexavalent oxidation state, irradiating the hydrocarbon reactant and the supported chromium catalyst 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. The supported chromium catalyst can be formed by heat treating a supported chromium precursor, contacting a chromium precursor with a solid support while heat treating, or heat treating a solid support and then contacting a chromium precursor with the solid support.

摘要： An apparatus and method of producing methanol includes reacting a heated hydrocarbon-containing gas and an oxygen-containing gas in a reactor; to provide a product stream comprising methanol; and transferring heat from the product stream to the hydrocarbon-containing gas to heat the hydrocarbon containing gas. After removing methanol and CO2 from the product stream, unprocessed hydrocarbons are mixed with the hydrocarbon containing gas fro reprocessing through the reactor.

摘要： A liquid phase selective oxidation process is described. The process involves the partial oxidation of alkanes to partially oxidized products. A lower alkane, a solvent, and a soluble metal catalyst are contacted in the presence of an oxidizing agent in a reaction zone under partial oxidation conditions to produce the partially oxidized products. The partially oxidized products include one or more of lower alkyl alcohols, lower alkyl ketones, and lower alkyl acetates. The soluble metal catalyst is a soluble metal salt of cobalt, manganese, chromium, titanium, copper, nickel, vanadium, iron, molybdenum, tin, cerium, zirconium, or combinations thereof, and the promoter comprises a bromine source, an imide source, or combinations thereof.
