Reactors and methods for producing solid carbon materials

1. A reactor for producing a solid carbon material, comprising:

at least one reaction chamber configured to produce a solid carbon material and water vapor through a reduction reaction between at least one carbon oxide and at least one gaseous reducing material in the presence of at least one catalyst material structure comprising a catalyst material and at least partially extending through the at least one reaction chamber;

at least one cooling chamber operatively communicating with the at least one reaction chamber and configured to condense the water vapor produced in the at least one reaction chamber, wherein the at least one cooling chamber is configured to have an operating temperature of less than or equal to about 50° C.;

at least one porous material structure configured to support at least one layer of the at least one catalyst material within the at least one reaction chamber and to separate at least one region of the at least one reaction chamber from at least one other region of the at least one reaction chamber; and

at least one conveying mechanism configured to transport the at least one catalyst material structure through the at least one reaction chamber.

2. The reactor of claim 1 , wherein the at least one reaction chamber is configured to produce the solid carbon material through at least one of a Bosch reaction, a Boudouard reaction, and a methane reduction reaction.

3. The reactor of claim 1 , wherein the at least one reaction chamber is configured to withstand an operating temperature greater than or equal to about 450° C.

4. The reactor of claim 1 , further comprising a heat exchange zone operatively associated with each of at least one effluent gas line and at least one return gas line extending between the at least one reaction chamber and the at least one cooling chamber, and configured to exchange heat between the at least one effluent gas line and the at least one return gas line.

5. The reactor of claim 1 , further comprising at least one prime mover operatively associated with each of the at least one reaction chamber and the at least one cooling chamber and configured to promote a flow of gases through the reactor.

6. The reactor of claim 1 , wherein the at least one layer of the at least one catalyst material is on the at least one porous material structure.

7. The reactor of claim 1 , wherein the at least one layer of the at least one catalyst material is between two layers of the at least one porous material structure.

8. The reactor of claim 1 , wherein the at least one porous material structure is coupled to an outer shell configured to at least partially define the at least one reaction chamber.

9. The reactor of claim 8 , wherein the outer shell comprises at least one reaction gas inlet, at least one reaction product outlet, at least one catalyst material inlet, and at least one catalyst material outlet.

10. The reactor of claim 8 , wherein the at least one reaction chamber comprises a plurality of reaction chambers.

11. The reactor of claim 1 , wherein the at least one catalyst material comprises at least one catalyst material structure at least partially extending through the at least one reaction chamber.

12. The reactor of claim 11 , further comprising at least one conveying mechanism configured to transport the at least one catalyst material structure through the at least one reaction chamber.
