Disclosed herein are unmixed fuel processors and methods for using the same. In one embodiment, an unmixed fuel processor comprises: an oxidation reactor comprising an oxidation portion and a gasifier, a CO2 acceptor reactor, and a regeneration reactor. The oxidation portion comprises an air inlet, effluent outlet, and an oxygen transfer material. The gasifier comprises a solid hydrocarbon fuel inlet, a solids outlet, and a syngas outlet. The CO2 acceptor reactor comprises a water inlet, a hydrogen outlet, and a CO2 sorbent, and is configured to receive syngas from the gasifier. The regeneration reactor comprises a water inlet and a CO2 stream outlet. The regeneration reactor is configured to receive spent CO2 adsorption material from the gasification reactor and to return regenerated CO2 adsorption material to the gasification reactor, and configured to receive oxidized oxygen transfer material from the oxidation reactor and to return reduced oxygen transfer material to the oxidation reactor.

What is claimed is: 1. An unmixed fuel processor, comprising: an oxidation reactor comprising an oxidation portion and a gasifier, wherein the oxidation portion comprises an air inlet, effluent outlet, and an oxygen transfer material that undergoes an exothermic oxidation reaction with air introduced into the oxidation reactor through the air inlet to produce oxygen depleted gas at a high temperature and high pressure that exits the oxidation reactor through the effluent outlet, and wherein the gasifier comprises a solid hydrocarbon fuel inlet, a solids outlet, and a syngas outlet, a CO2 acceptor reactor comprising a water inlet, a hydrogen outlet, and a CO2 sorbent, wherein the CO2 acceptor reactor is configured to receive syngas from the gasifier; a regeneration reactor comprising a water inlet and a CO2 stream outlet, wherein the regeneration reactor is configured to receive spent CO2 adsorption material from the CO2 acceptor reactor and to return regenerated CO2 adsorption material to the CO2 acceptor reactor, and configured to receive oxidized oxygen transfer material from the oxidation reactor and to return reduced oxygen transfer material to the oxidation reactor. 2. The processor of claim 1, wherein the oxidation reactor is configured such that during operation of the processor, a solids accumulation area disposed adjacent the solids outlet is maintained at a temperature that enables solids to accumulate in the solids accumulation area, and to enable gasification and reaction of a solid hydrocarbon fuel in a gasification area. 3. The processor of claim 1, wherein the gasifier further comprises a catalyst. 4. The processor of claim 3, wherein the catalyst comprises a compound selected from the group consisting of iron, nickel, calcium, magnesium, and combinations comprising at least one of the foregoing. 5. The processor of claim 1, wherein the regeneration reactor is further configured to receive syngas from the gasifier. 6. The processor of claim 1, wherein the oxidation reactor is configured to allow heat exchange between air entering the oxidation portion and the gasifier. 7. The processor of claim 1, wherein the oxidation reactor further comprises a heat exchanger disposed in thermal communication with a solids accumulation area. 8. A method for operating an unmixed fuel processor, comprising: introducing a solid hydrocarbon fuel to a gasifier of an oxidation reactor, wherein the oxidation reactor comprises an oxidation portion, wherein the oxidation portion comprises an oxygen transfer material, and wherein the gasifier comprises a solids accumulation area and a solids outlet; oxidizing an oxygen transfer material in the oxidation portion and forming an oxygen depleted stream; gasifying the solid hydrocarbon fuel; reacting the solid hydrocarbon fuel to form syngas; removing solids from the syngas; introducing the syngas and water to a CO2 acceptor reactor; adsorbing the CO2 with a CO2 sorbent to produce a spent CO2 sorbent and form a H2 stream; and regenerating the spent CO2 sorbent and reducing the oxidized oxygen transfer material in a regeneration reactor and forming a CO2 stream. 9. The method of claim 8, wherein the solid hydrocarbon fuel is reacted with a reaction gas to form the syngas, and wherein the reaction gas is selected from the group consisting of water, CO2, and combinations comprising at least one of the foregoing gases. 10. The method of claim 8, further comprising introducing a portion of the syngas to the regeneration reactor. 11. The method of claim 8, wherein the solids accumulation area has an average temperature of less than or equal to about 700° C., and the remainder of the gasifier has an average temperature of about 700° C. to about 1,200° C. 12. The method of claim 8, further comprising directing the oxygen depleted stream to a turbine. 13. The method of claim 8, further comprising recycling at least a portion of the CO2 stream to a UFP component selected from the group consisting of the CO2 acceptor reactor, the regeneration reactor, the gasifier, and combinations comprising at least one of the foregoing UFP components. 14. The method of claim 8, further comprising cooling a solids accumulation area of the gasifier. 15. The method of claim 14, further comprising introducing air to the oxidation portion, wherein the air is heated with heat from the gasifier prior to entering the oxidation portion. 16. The processor of claim 1, wherein at least a portion of the gasifier is disposed relative to the oxidation portion of the oxidation such that the exothermic oxidation of the oxidation transfer material provides energy for gasification of a solid hydrocarbon fuel within a gasifier area of the gasifier.
