Abstract: An example method for operating an energy recovery system may comprise providing a reducing gas stream to an inlet of the energy recovery system, contacting redox particles with the reducing gas stream, whereupon the at least one reducing gas species undergoes a chemical reaction with the redox particles to generate carbon dioxide (CO2) and/or steam (H2O) obtaining a first product stream from the energy recovery system, providing an oxidizing gas stream comprising steam (H2O) to the energy recovery system such that hydrogen gas (H2) is generated, and obtaining a second product stream from the energy recovery system, the second product stream comprising hydrogen gas (H2). The reducing gas stream may comprise at least one reducing gas species comprising at least one of carbon monoxide (CO), methane (CH4), hydrocarbons (C2+), hydrogen gas (H2), and carbon dioxide (CO2). The first product stream may comprise carbon dioxide (CO2) and steam (H2O).

Abstract: A system used for converting multiple fuel feedstocks may include three reactors. The reactor system combination can be so chosen that one of the reactors completely or partially converts the fuel while the other generates the gaseous product required by utilizing the gaseous product from the second reactor. The metal-oxide composition and the reactor flow-patterns can be manipulated to provide the desired product. A method for optimizing the system efficiency where a pressurized gaseous fuel or a pressurized utility is used for applications downstream can be used to any system processing fuels and metal-oxide.

Abstract: 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.

Abstract: A system for converting carbonaceous fuels is provided. The system includes a gaseous fuel conversion reactor, a solid fuel conversion reactor, and a fuel pretreatment fluidized bed reactor disposed between the gaseous fuel conversion reactor and the solid fuel conversion reactor. The fuel pretreatment fluidized bed reactor devolatilizes a solid fuel using heat to produce an off-gas and a devolatilized solid fuel. The gaseous fuel conversion reactor converts the off-gas from the fuel pretreatment fluidized bed reactor to a product gas stream comprising carbon dioxide and water. The solid fuel conversion reactor receives a mixture of oxygen carrier solids and devolatilized solid fuel from the pretreatment reactor discharge and reduces the devolatilized solid fuel with the oxygen carrier solids to convert the devolatilized solid fuel to an intermediate gas.

Abstract: 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.
