    Abstract: A system is set forth for the exothermic generation of soot depleted syngas comprising (i) reacting a hydrocarbon-containing fuel with an oxygen containing gas in a first reactor to produce the syngas and byproducts comprising CO2, H2O and soot; and (ii) introducing the syngas and byproducts into a second reactor containing a non-carbonaceous material that traps the soot for a sufficient time such that the majority of the byproduct soot is gasified via reaction with the byproduct CO2 and/or H2O to produce a syngas stream that is depleted in the soot. The system is particularly suitable for the practice of heat exchange reforming wherein a portion of the heat is recovered from the soot depleted syngas stream and used as at least a portion of the heat to facilitate the additional production of syngas via the (endothermic) catalytic reforming of natural gas and steam.

    Abstract: A process is provided which includes the steps of providing a CO-SER unit, feeding a feed gas of an equimolar mix of CO2 and H2 with a slight excess of CO2 to the CO-SER unit to produce a CO-SER product gas of CO, a small amount of CO2, and substantially no H2 at high pressure, providing a TSA unit having a plurality of adsorber vessels, each adsorber vessel having an adsorbent capable of selectively adsorbing CO2, the adsorber vessel being at high pressure and ambient temperature, and feeding the CO-SER product gas to one of the adsorber vessels in the TSA unit to selectively remove CO2 gas to produce a TSA product gas that is of high purity and of high pressure. The feeding continues to the one adsorber vessel until a point prior to CO2 breakthrough occurring. The process further includes regenerating any adsorber vessels having adsorbent that is substantially spent.
