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&#xb0; C. to 1000&#xb0; 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 CaSOat a temperature of 350&#xb0; C. to 1000&#xb0; C. to produce one or more olefins comprising ethylene and coproducing water.

Enhanced oxygen transfer agent systems for oxidative dehydrogenation of hydrocarbons

Aspects of the invention relate to enhanced oxygen transfer agent systems and methods of use thereof. 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&#xb0; C. to 1000&#xb0; C. The oxygen transfer agent comprising an oxygen-donating chalcogen agent comprised of at least one of S, Se, or Te and a reducible metal oxide. The chalcogen having an oxidation state greater than +2. According to another aspect, a method for producing one or more olefins by partial combustion of a hydrocarbon feed includes partially combusting a hydrocarbon feed comprised of one or more alkanes by contacting the hydrocarbon feed with an oxygen transfer agent comprising CaS0at a temperature of 350&#xb0; C. to 1000&#xb0; C. to produce one or more olefins comprising ethylene and coproducing water.

Aspects of the invention relate to producing olefins by oxidative dehydrogenation cocracking of a hydrocarbon feed. In one embodiment, the method includes oxidative cocracking a hydrocarbon feed comprised of at least one alkane having a carbon chain of five or more and at least one alkane having a carbon chain of four or less by contacting the hydrocarbon feed with a metal oxide, such that the cracking of the at least one alkane having a carbon chain of four or less produces olefins and is exothermic, and the cracking of the at least one alkane having a carbon chain of five or more produces olefins and is endothermic. The method further includes utilizing the energy produced from the exothermic cracking of the alkane having a carbon chain of four or less for the endothermic cracking of the alkane having a carbon chain of five or more, and collecting the product.
