Abstract: A method of treating a carbonaceous material is disclosed. The method includes heating the carbonaceous material in a reactor with microwave energy, at a pressure less than about 5 atmospheres, to generate a mixture comprising char, oil and gas.

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.
