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.

1. A method of producing syngas, the method comprising: providing a counter-current contact mode between a first metal oxide and a first fuel in a first reactor to reduce the first metal oxide to a second metal oxide, wherein the first reactor comprises a plurality of oxygen carrying particles and wherein the plurality of oxygen carrying particles comprises the first metal oxide;oxidizing the second metal oxide to a third metal oxide in a second reactor, and reducing the third metal oxide to a fourth metal oxide with a second fuel to provide a partially or fully oxidized gaseous fuel comprising one or more of CO, CO2, H2, and H2O, wherein the second metal oxide is oxidized to the third metal oxide using an enhancing gas of CO2 and H2O, the partially or fully oxidized gaseous fuel, or a combination thereof, to generate syngas and wherein the second reactor is in communication with the first reactor; andregenerating the first metal oxide by oxidizing the fourth metal oxide with an oxygen source in a third reactor, wherein the third reactor is in communication with the second reactor. 2. The method of claim 1, wherein the counter-current contact mode between the first metal oxide and the first fuel is such that the first metal oxide moves downward and the first fuel moves upward. 3. The method of claim 1, wherein the method further comprises introducing the first metal oxide to the top of the first reactor, and introducing the first fuel to the bottom of the first reactor. 4. The method of claim 1, wherein the method further comprises providing a counter-current contact mode between the second metal oxide and the enhancing gas in the second reactor, and providing a counter-current contact mode between the third metal oxide and the second fuel in the second reactor. 5. The method of claim 4, wherein the method further comprises introducing the second metal oxide to the top of the second reactor, introducing the enhancing gas to the middle of the second reactor, and introducing the second fuel to the bottom of the second reactor. 6. The method of claim 1, wherein the method further comprises providing a co-current contact mode between the second metal oxide and the enhancing gas in the second reactor, and providing a co-current contact mode between the third metal oxide and the second fuel in the second reactor. 7. The method of claim 6, wherein the method further comprises introducing the second metal oxide to the top of the second reactor, introducing the enhancing gas to the middle of the second reactor, and introducing the second fuel to the top of the second reactor. 8. The method of claim 6, wherein the method further comprises introducing the second metal oxide to the top of the second reactor, introducing the enhancing gas to the top of the second reactor, and introducing the second fuel to the top or the middle of the second reactor. 9. The method of claim 1, wherein at least a portion of the enhancing gas is derived from the first reactor resulting from the reduction of the first metal oxide with the first fuel. 10. The method of claim 1, wherein at least a portion of the enhancing gas is derived from oxidation of a carbon-containing or hydrogen-containing source in the third reactor, a fourth reactor, or a combination thereof. 11. The method of claim 1, wherein the third reactor is in communication with the first reactor, wherein at least a portion of the second metal oxide is circulated directly to the third reactor, and oxidation of a carbon-containing or hydrogen-containing source with an oxygen source in the third reactor generates a stream of enhancing gas, and wherein at least a portion of the enhancing gas generated in the third reactor is used in the second reactor as an enhancing gas. 12. The method of claim 1, wherein the method further comprises generating a stream of enhancing gas comprising CO2 and H2O in a fourth reactor, and wherein the fourth reactor is in communication with the first reactor. 13. The method of claim 12, wherein at least a portion of the enhancing gas generated in the fourth reactor is used in the second reactor as an enhancing gas. 14. The method of claim 1, wherein the first fuel is a solid fuel selected from biomass, coal, pet-coke, solid hydrocarbon-based waste products, or a combination thereof. 15. The method of claim 1, wherein the first fuel is a gaseous fuel selected from natural gas, gasified coal, a light hydrocarbon off-gas stream, or a combination thereof. 16. The method of claim 1, wherein the second fuel is a solid fuel selected from biomass, coal, pet-coke, solid hydrocarbon-based waste products, or a combination thereof. 17. The method of claim 1, wherein the second fuel is a gaseous fuel selected from natural gas, gasified coal, a light hydrocarbon off-gas stream, or a combination thereof. 18. The method of claim 1, wherein the second reactor is in communication with a Fischer-Tropsch or methanol synthesis system that produces a light hydrocarbon tail-gas, wherein the second reactor provides syngas to the Fischer-Tropsch or methanol synthesis system and the light hydrocarbon tail-gas is optionally recycled to first reactor, the second reactor, or a combination thereof. 19. The method of claim 1, wherein the first metal oxide has formula FeOaTix or FeOaAlx,the second metal oxide has formula FeObTix or FeObAlx,the third metal oxide has formula FeOcTix or FeObAlx, andthe fourth metal oxide has formula FeOdTix or FeOdAlx,wherein 1.5>a>b, bd, 1.5>c, and x is 0.01 to 5. 20. The method of claim 1, wherein the first metal oxide has formula FeOaTiO2 or FeOaAl2O3,the second metal oxide has formula FeObTiO2 or FeObAl2O3,the third metal oxide has formula FeOcTiO2 or FeOcAl2O3, andthe fourth metal oxide has formula FeOdTiO2 or FeOdAl2O3,wherein 1.5>a>b, bd, and 1.5>c.
