The disclosure provides for the separation and combustion of at least one hydrocarbon, oxygenate, sulfur compound, and or nitrogen compound, from industrial gas or gasification derived syngas to generate steam. A gasification process and a gas fermentation process may be integrated using tail gas from the fermentation process for the flame to combust tar and other compounds from the syngas generated by a gasification process. Integration may be achieved by removing tar and other compounds from industrial gas or gasification derived syngas using an adsorbent and regenerating the adsorbent using tail gas from the gas fermentation process. Tail gas enriched with the desorbed tar and other compounds may be used to generate steam in a steam boiler and the steam may be used for a variety of purposes including power generation to power, for example, a compressor of the gas fermentation process.

Systems and methods are provided for co-processing of plastic waste with biomass to generate gas phase product streams with improved properties. The systems and methods can include having a high temperature swing adsorption process integrated with a pyrolysis process, gasification process, or other thermal conversion process, so that CO.sub.2 can be removed from at least a portion of the effluent. This can facilitate capture of CO.sub.2 when using pyrolysis, gasification, or other thermal conversion to generate a hydrogen-containing stream. Additionally, the integrated system and/or method can allow for production of multiple product streams having desirable ratios of hydrogen to carbon oxides.

A system for removing impurities from post-combustion gas includes an oxidizer and a reducer operatively connected to the oxidizer, the reducer configured to receive the post-combustion gas. The system further includes a CLOU material capable of selective circulation between the oxidizer and reducer. The CLOU material further oxidizes impurities present in the post-combustion gas to reduce or remove the same.

The present disclosure relates to a power production system that is adapted to achieve high efficiency power production with carbon capture when using a solid or liquid hydrocarbon or carbonaceous fuel. More particularly, the solid or liquid fuel first is partially oxidized in a partial oxidation reactor that is configured to provide an output stream that is enriched in methane content. The resulting partially oxidized stream can be cooled, filtered, additionally cooled, and then directed to a combustor of a power production system as the combustion fuel. The partially oxidized stream is combined with a compressed recycle CO.sub.2 stream and oxygen. The combustion stream is expanded across a turbine to produce power and passed through a recuperator heat exchanger. The recycle CO.sub.2 stream is compressed and passed through the recuperator heat exchanger and optionally the POX heat exchanger in a manner useful to provide increased efficiency to the combined systems.
