Abstract: A method for converting one or more hydrocarbons includes feeding a fluid comprising one or more light alkanes to a reactor system, and producing one or more oxygenates from the one or more light alkanes in the reactor system. The reactor system comprises a reactor containing at least one catalyst, the at least one catalyst comprises one or more oxides of molybdenum, vanadium, niobium, cerium, titanium, zirconium, and one or more precious metals. An oxygenate productivity is higher than about 50 g/kg cat.h after 100 hours of time on stream.

Abstract: A process is disclosed that includes brominating a C2, C3, C4, C5 or C6 alkane with elemental bromine to form a bromo-alkane. The bromo-alkane is reacted to form a C2, C3, C4, C5 or C6 alkene and HBr. The HBr is oxidized to form elemental bromine.

Abstract: A method comprising: providing an alkyl halide stream; contacting at least some of the alkyl halides with a coupling catalyst to form a product stream comprising higher hydrocarbons and hydrogen halide; contacting the product stream with a solid reactant to remove at least a portion of the hydrogen halide from the product stream; and reacting the solid reactant with a source of oxygen to generate a corresponding halogen.

Abstract: A process is provided for separating one or more light gases from bromine or chlorine using one or more physical separations and contact with a chemical scrubber to recover additional halogen. In one aspect, the process comprises (a) providing a feed of halogen containing one or more light gases to a distillation column or flash vaporizer; (b) operating the distillation column or flash vaporizer to separate the feed into (i) a first liquid containing a major amount of halogen and no more than a minor amount of light gas(es), and (ii) a first vapor containing a major amount of light gas(es) and no more than a minor amount of halogen; and (c) providing the vapor to a chemical scrubber to recover halogen from the vapor.

Abstract: An improved continuous process for converting methane, natural gas, or other hydrocarbon feedstocks into one or more higher hydrocarbons or olefins by continuously cycling through the steps of alkane halogenation, product formation (carbon-carbon coupling), product separation, and regeneration of halogen is provided. Preferably, the halogen is continually recovered by reacting hydrobromic acid with air or oxygen. The invention provides an efficient route to aromatic compounds, aliphatic compounds, mixtures of aliphatic and aromatic compounds, olefins, gasoline grade materials, and other useful products.

Abstract: A process for the removal of a pollutant from a gas is provided that includes contacting a gas comprising a pollutant with a cataloreactant wherein the cataloreactant reacts with the pollutant and wherein an oxidation state of the cataloreactant is reduced. The cataloreactant may be regenerated with an oxidizing agent.
