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: Exemplary chemical looping systems include at least one type of active solid particles and inert solid particles that may be provided between various reactors in exemplary systems. Certain chemical looping systems may include a reducer reactor in fluid communication with a combustor reactor. Some chemical looping systems may additionally include an oxidizer reactor in fluid communication with the combustor reactor and the reducer reactor. Generally, active solid particles are capable of cycling between a reduction reaction and an oxidation reaction. Generally, inert solid particles are not reactants in either the reduction reaction or the oxidation reaction.

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.
