Abstract: Enhanced oxygen transfer agent systems and methods of use thereof are provided. According to one aspect, a method for producing olefins from a hydrocarbon feed includes the step of contacting a hydrocarbon feed comprised of one or more alkanes with an oxygen transfer agent at a temperature of 350° C. to 1000° C. The oxygen transfer agent includes an oxygen-donating chalcogen agent including at least one of S, Se, or Te and a reducible metal oxide. The chalcogen has an oxidation state greater than +2. A method for producing one or more olefins by partial combustion of a hydrocarbon feed is provided. The method includes partially combusting a hydrocarbon feed comprised of one or more alkanes by contacting the hydrocarbon feed with an oxygen transfer agent comprising CaSO4 at a temperature of 350° C. to 1000° C. to produce one or more olefins comprising ethylene and coproducing water.

Abstract: A method of removing CO from a mixture of CO and saturated or unsaturated hydrocarbons is provided. In one embodiment, the method is to contact a feed stream with an oxygen transfer agent; and then oxidize at least a portion of the CO to CO2 to produce a stream enriched in CO2. The saturated and unsaturated hydrocarbons in the feed are not further oxidized during the oxidation. The oxygen transfer agent includes at least one of: i) water; ii) at least one reducible metal oxide; iii) at least one reducible chalcogen; or mixtures thereof. In another embodiment, the CO is converted to methane. The unsaturated hydrocarbons in the feed are not hydrogenated. In both of these alternatives, the CO2 or methane are then removed. Systems for removing the CO are also provided.

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 is provided for producing at least one olefin by oxidative dehydrogenation of a hydrocarbon feed. The method includes the steps of contacting a hydrocarbon feed, which includes at least one alkane, and a steam feed with an oxygen transfer agent under a pressure of 1.1 bar to 800 bar to produce at least one olefin. The oxygen transfer agent contains a metal oxide that acts as an oxidizing agent to oxidize the at least one alkane. Additionally, the method includes the step of collecting a product stream containing the at least one olefin.
