Abstract: A method of removing CO from a mixture of CO and saturated and unsaturated hydrocarbons CO to CO2 is provided. In one embodiment, the method is to contact 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.
