Exemplary oxygen carrier particles may comprise a mesoporous support and a plurality of metal oxide-based nanoparticles immobilized on the mesoporous support. The plurality of metal oxide-based nanoparticles may comprise 10 volume percent to 80 volume percent of mesopores in the mesoporous support. A reactor may comprise a feedstock inlet in fluid communication with a carbonaceous feedstock source, a product stream outlet, and oxygen carrier particles. Exemplary reactors may be operated by providing a carbonaceous feedstock to an inlet of the reactor, providing oxygen carrier particles within the reactor, and collecting a product stream from an outlet of the reactor.

Mesoporous support-immobilized metal oxide-based nanoparticles

Exemplary reactor systems may include multiple reactors in fluid communication. Oxygen carrier particles comprising a support material and metal oxide can be provided to a first reactor along with flue gas comprising carbon dioxide (CO2). An output of the first reactor is free or substantially free of carbon dioxide (CO2). The oxygen carrier particles can then be provided to one or more reactors in the system along with a hydrocarbon stream and, in some instances, an oxidizing stream. Outlets from these one or more reactors may include hydrogen gas (H2), carbon monoxide (CO), and/or other species, depending upon the content of the hydrocarbon streams and the oxidizing streams.

Redox reaction facilitated carbon dioxide capture from flue gas and conversion to carbon monoxide

Systems and methods generally involve processing a gaseous reducing agent and a gaseous reforming agent to produce syngas in the presence of a stable-phase change metal-oxide based oxygen carrier. During operation, an oxygen content is measured for a reactor input stream and a reactor output stream. A percent oxygen depletion of the metal oxide is determined using an initial oxygen content of the metal oxide, the oxygen content of the input stream, and the oxygen content of the output stream. Based on the percent oxygen depletion, a mole ratio of reducing gas to oxidant in the input stream may be adjusted accordingly.

Systems, methods and materials for stable phase syngas generation

Systems and methods use bimetallic alloy particles for converting hydrogen sulfide (HS) to hydrogen (H) and sulfur (S), typically during multiple operations. In a first operation, metal alloy composite particles can be converted to a composite metal sulfide. In a second operation, composite metal sulfide from the first operation can be regenerated back to the metal alloy composite particle using an inert gas stream. Pure, or substantially pure, sulfur can also be generated during the second operation.

Systems, methods and materials for hydrogen sulfide conversion

Systems and methods include providing a gaseous alkane input stream and metal sulfide (MSx) particles that can react with an alkane in the gaseous alkane input stream to generate an alkene, a reduced metal sulfide (MSx&#x2212;1) particle, and at least one of: hydrogen sulfide (H2S) and at least one sulfur containing compound selected from: S2, CS, and CS2. A product stream can be collected that includes the alkene and at least one of: hydrogen sulfide (H2S) and the at least one sulfur containing compound. A reduced metal sulfide (MSx&#x2212;1) particle reacts with sulfur in a sulfur stream and can generate the metal sulfide (MSx) particle and hydrogen (H2).

Alkene generation using metal sulfide particles

Systems and methods include providing a gaseous alkane input stream and metal sulfide (MSx) particles that can react with an alkane in the gaseous alkane input stream to generate an alkene, a reduced metal sulfide (MSx-1) particle, and at least one of: hydrogen sulfide (H2S) and at least one sulfur containing compound selected from: S2, CS, and CS2. A product stream can be collected that includes the alkene and at least one of: hydrogen sulfide (H2S) and the at least one sulfur containing compound. A reduced metal sulfide (MSx-1) particle reacts with sulfur in a sulfur stream and can generate the metal sulfide (MSx) particle and hydrogen (H2).

A reactor configuration is proposed for selectively converting gaseous, liquid or solid fuels to a syngas specification which is flexible in terms of H/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 COstream 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 COsuch that, carbon efficiency of the system is maximized.

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 (O) and a reduced metal oxide particle is generated. Then a second gaseous product stream is collected, where the second gaseous product stream includes oxygen (O) gas.
