The present invention provides a method for recovering a natu-ral gas contaminated with high levels of carbon dioxide. A gas containing methane and carbon dioxide is extracted from a reservoir containing natural gas, where carbon dioxide comprises at least 50 vol.% of the extracted gas. The ex-tracted gas is oxidized with an oxygen containing gas in the presence of a par-tial oxidation catalyst at a temperature of less than 600°C to produce an oxidation product gas containing hydrogen, carbon monoxide, and carbon dioxide. The oxi-dation product gas is then utilized to pro-duce a liquid hydrocarbon or a liquid hy-drocarbon oxygenate.
La présente invention concerne un procédé de récupération dun gaz naturel contaminé avec des taux élevés de dioxyde de carbone. Un gaz contenant du méthane et du dioxyde de carbone est extrait dun réservoir contenant un gaz naturel, où le dioxyde de carbone comprend au moins 50 % en volume du gaz extrait. Le gaz extrait est oxydé avec un gaz contenant de loxygène en présence dun catalyseur doxydation partielle à une température inférieure à 600 °C pour produire un gaz de produit doxydation contenant de lhydrogène, du monoxyde de carbone et du dioxyde de carbone. Le gaz de produit doxydation est ensuite utilisé pour produire un hydrocarbure liquide ou un hydrocarbure oxygéné liquide.
