24 Claims

1. A method of converting CO to CO₂comprising,

a) contacting a first process stream comprising the CO and at least one of C₁to C₁₂saturated and unsaturated hydrocarbons with an oxygen transfer agent; and

b) oxidizing at least a portion of the CO to CO₂and reducing at least a portion of the oxygen transfer agent to a reduced oxygen transfer agent, at reaction conditions, to provide a second process stream comprising the CO₂, the reduced oxygen transfer agent, and the at least one of C₁to C₁₂saturated and unsaturated hydrocarbons; wherein the C₁to C₁₂saturated and unsaturated hydrocarbons are not further oxidized; and

c) contacting the reduced oxygen transfer agent with a third process stream comprising molecular oxygen to provide a regenerated oxygen transfer agent

wherein the oxygen transfer agent comprises at least one reducible metal oxide.
