Abstract: A process and plant for producing a high purity CO2 product, comprising: providing a CO2-rich stream containing hydrocarbons, hydrogen and/or CO, combining it with a stream rich in methane (CH4), and mixing it with oxygen, thereby forming a CO2/O2- mixture; subjecting the CO2/O2- mixture to a catalytic oxidation step, thereby producing a purified stream having a higher CO2 and/or H2O concentration; removing H2O from said purified stream, for producing said high purity CO2 product stream. The CO2-rich stream is for instance derived from the CO2-removal section of a plant for producing hydrogen.
