1. A method of converting CO to CO2 comprising,
a1) oxidative coupling of methane or oxidative dehydrogenation of hydrocarbons at hydrocarbon oxidation reaction conditions to produce a first process stream comprising the CO and at least one of C1 to C12 saturated or unsaturated hydrocarbons;
a) contacting the first process stream comprising the CO and the at least one of C1 to C12 saturated or unsaturated hydrocarbons with an oxygen transfer agent; and
b) oxidizing at least a portion of the CO to CO2 and 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 C1 to C12 saturated or unsaturated hydrocarbons;
wherein:
the C1 to C12 saturated or unsaturated hydrocarbons are not further oxidized in step b);
the hydrocarbon oxidation reaction conditions include the presence of less than 5 wt % of O2 with respect to the total amount of CO in the first process stream; and
the oxygen transfer agent in step b) comprises water.
