Abstract: A reactor configuration is proposed for selectively converting gaseous, liquid or solid fuels to a syngas specification which is flexible in terms of H2/CO ratio. This reactor and system configuration can be used with a specific oxygen carrier to hydro-carbon fuel molar ratio, a specific range of operating temperatures and pressures, and a co-current downward moving bed system. The concept of a CO2 stream injected in-conjunction with the specified operating parameters for a moving bed reducer is claimed, wherein the injection location in the reactor system is flexible for both steam and CO2 such that, carbon efficiency of the system is maximized.

Abstract: Systems and methods use oxygen uncoupling metal oxide material for decomposition of NOx. A gaseous input stream comprising NOx is contacted with a metal oxide particle, generating nitrogen (N2) gas and an oxidized metal oxide particle. After contacting the first gaseous input stream with the metal oxide particle, a first gaseous product stream is collected. The first gaseous product stream includes substantially no NOx. A second gaseous input stream comprising at least one sweeping gas is also contacted with the oxidized metal oxide particle. After contacting the oxidized metal oxide particle, the sweeping gas includes oxygen (O2) and a reduced metal oxide particle is generated. Then a second gaseous product stream is collected, where the second gaseous product stream includes oxygen (O2) gas.
