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 CO.sub.2 to produce a stream enriched in CO.sub.2. 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 CO.sub.2 or methane are then removed. Systems for removing the CO are also provided.

The invention relates to a process for the production of ethylene in an integrated configuration comprising (i) a steam cracker configuration which comprises a steam cracker unit, a water condensation unit and a carbon dioxide removal unit and (ii) an oxidative dehydrogenation (ODH) configuration which comprises an ODH unit and a water condensation unit, wherein an effluent coming from the ODH configuration, which effluent comprises unconverted ethane and ethylene, is fed to the steam cracker configuration at a position which is downstream of the steam cracker unit, and wherein unconverted oxygen, carbon monoxide and acetylene are removed from at least a portion of the stream coming from the ODH unit by oxidation of carbon monoxide and acetylene into carbon dioxide in an oxidation unit which is located at a position (a) which is downstream of the ODH unit, and (b) which is downstream of the steam cracker unit and upstream of the carbon dioxide removal unit of the steam cracker configuration.

“Green” methods of preparing oxygenated products, animal feed, and fertilizer are disclosed. Desired oxygenated products include, but are not limited to, ethanol, acetic acid, butyrate, butanol, propionate, propanol, or any combination thereof. The methods use synthesis gas (syngas), which can be produced from processing of coal, natural gas, and/or biomass. The syngas contains some combination of hydrogen, carbon monoxide, and/or carbon dioxide. The method entails blending the syngas with purge (tail) gases from industrial processes and/or with hydrogen gas, e.g., produced from renewable sources. The resulting mixture is a H.sub.2-enriched syngas that is fermented by microorganisms that are well suited to ferment hydrogen-rich gases. Byproducts from the method can also be recovered. The disclosure also provides methods of preparing material fertilizer and animal feed, respectively. By repurposing purge gases so they are not emitted into the environment and/or using hydrogen from renewable sources, the disclosed methods are environmentally-friendly.

A process (100) is proposed for the production of one or more olefins, in which a reaction feed containing oxygen and one or more paraffins is formed and in which a part of the oxygen in the reaction feed is reacted with a part of the one or more paraffins to form the one or more olefins by an oxidative process, to obtain a process gas, the process gas containing at least the unreacted part of the one or more paraffins and oxygen, the one or more olefins, one or more acetylenes, carbon dioxide and water. The process comprises subjecting the process gas or a gas mixture formed using at least a part of the process gas partially or completely to a condensate separation (2), a compression (3), an at least partial removal (4) of the oxygen and acetylene(s) and to one or more stages of a carbon dioxide removal (5) in the order given herein, wherein the at least partial removal (4) of the oxygen and of the acetylene(s) is performed at the same time and by a catalytic conversion using a catalyst comprising copper oxide or ruthenium, and wherein the catalytic conversion is performed at least in part in the form of a hydrogenation. A corresponding plant is also the subject of the present invention.
