FIELD: gas industry.
SUBSTANCE: invention relates to a method of processing a carbon dioxide-enriched gas mixture formed when producing a synthesis gas. Method involves passing a raw material containing hydrocarbon through pipes located in a heating chamber of a steam reforming heated by reactor burners, herewith the raw material is converted into a crude synthesis gas containing hydrogen, carbon monoxide, carbon dioxide, as well as hydrocarbons, separation from the crude synthesis gas of a gas mixture enriched with carbon dioxide containing oxidizing substances, thermal treatment of part of the gas mixture enriched with carbon dioxide containing oxidizing substances in an oxygen-containing atmosphere and combustion of the oxidizing substances.
EFFECT: invention provides efficient processing a carbon dioxide-enriched gas mixture.
