A gaseous mixture (101), comprising CO 2 , H 2 , H 2 S and optionally CO, is separated into an H 2 or H 2 and CO product stream (103) (H 2 /CO product stream), and a CO 2 enriched stream (104) containing at least one combustible component selected from H 2 S, H 2 , CO and any additional combustible components present in the gaseous mixture. A support fuel stream (109), comprising one or more combustible components, is combusted to form a stable flame, and the CO 2 enriched stream and flame are contacted in the presence of sufficient O 2 to combust all or substantially all of the combustible component(s) present in said CO 2 enriched stream. A CO 2 product stream is formed from said combustion effluent (113). The support fuel stream may be generated from the process of generating or separating the gaseous mixture or from the H 2 /CO product stream. Where the CO 2 enriched stream contains H 2 S, the support fuel stream may also be a stream obtained off-site that comprises H 2 S. |
