Abstract

A solar thermochemical reactor includes an outer member, an inner member disposed within an outer member, wherein the outer member surrounds the inner member and wherein the outer member has an aperture for receiving solar radiation and wherein an inner cavity and an outer cavity are formed by the inner member and outer member and a reactive material capable of being magnetically stabilized wherein the reactive material is disposed in the outer cavity between the inner member and the outer member.

First claim

What is claimed is:

1. A method of using a solar thermochemical reactor comprising:
providing a solar thermochemical reactor including an outer member;
disposing an inner member within the outer member, wherein the outer member surrounds the inner member;
disposing a reactive material capable of being magnetically stabilized in between the outer member and the inner member;
applying a vacuum to the outer member after disposing the reactive material;
fluidizing the reactive material after applying the vacuum;
applying a magnetic field around the outer member after fluidizing the reactive material;
causing solar radiation to be received by the outer member while the magnetic field is applied;
carrying out a reduction reaction in the reactor to produce oxygen, the reduction reaction being carried out after causing the solar radiation to be received;
extracting the oxygen from the outer member;
disposing carbon dioxide and water onto the reactor material after extracting the oxygen;
carrying out an oxidation reaction in the reactor to produce carbon monoxide gas and hydrogen gas; and
extracting carbon monoxide gas and hydrogen gas from the outer member.

2. The method of claim 1 , wherein the reduction reaction is carried out at a temperature of less than or equal to 1500° C.

3. The method of claim 1 , wherein the oxidation reaction is carried out at an autothermal temperature.

4. The method of claim 1 , wherein the reduction reaction is carried out at a pressure of less than or equal to 10 −4 bar.

5. The method of claim 1 , wherein the oxidation reaction is carried out at atmospheric pressure.
