ABSTRACT A process for converting landfill gas to high concentration carbon dioxide gas involves combusting the landfill gas in admixture with oxygen or an oxygen rich gas in an internal combustion engine, gas turbine, boiler or other energy conversion device. In a first embodiment of the invention, a portion of the combusted exhaust gas is recycled in order to control the maximum temperature achieved during combustion. In a second embodiment of the invention, the majority of the methane in the landfill gas is separated and then the remaining gas is combusted in admixture with oxygen or oxygen rich gas in an internal combustion engine, gas turbine, boiler, or other energy conversion device. In this second embodiment, the peak temperature achieved in the combustor is controlled by appropriately selecting the amount of methane removed. The present invention increases the amount of carbon dioxide available from a given landfill gas by converting all or part of the contained methane to carbon dioxide and water. The gaseous carbon dioxide so produced is suitable as feed to a conventional carbon dioxide liquefaction plant for producing liquid food grade carbon dioxide.
