Abstract: A system for removing sulfur from a gaseous stream includes (a) a reaction bed for receiving the gaseous stream and for reacting sulfur dioxide and at least some of the hydrogen sulfide of the gaseous stream into elemental sulfur to provide an elemental sulfur stream and a first product stream; and (b) a circulating fluidized bed comprising (i) a first region for receiving the first product stream and using a sulfur adsorption material to adsorb and remove any remaining hydrogen sulfide from the first product stream to generate saturated sulfur adsorption material and a second product stream substantially free of sulfur; and (ii) a second region for receiving a regeneration stream and for using the regeneration stream to regenerate the saturated sulfur adsorption material and to generate the sulfur dioxide.

Abstract: Disclosed herein are systems and method for using unmixed fuel processors. In one embodiment, a system for using an unmixed fuel processor comprises: an unmixed fuel processor and a power generating unit. The unmixed fuel processor comprises: a gasification reactor, an oxidation reactor and a regeneration reactor. The gasification reactor comprises a CO2 sorbent material. The oxidation reactor comprises an oxygen transfer material. The regeneration reactor is configured to receive spent CO2 sorbent material from the gasification reactor and to return regenerated CO2 sorbent 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. The power generating unit configured to receive an oxygen depleted stream from the oxidation reactor and to produce electricity.
