摘要： 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).

摘要： 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.

摘要： 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.
