Abstract

The present disclosure relates to a reactor device (2) for converting powdered metal oxides, in particular metal oxides contained in regolith, to metal powder and molecular oxygen (O2), the reactor device (2) comprising a cathode reactor vessel (8) providing a receiving space (14) for the powdered metal oxides and adapted to be connected to an electron source (21) such that the powdered electrode oxides can be converted to the metal powder and oxygen ions (O2−) by the application of an electrical potential, and an anode reactor vessel (4) adapted to be connected to an electron sink (22) to attract the oxygen ions (O2−) travelling through an electrolyte (6) from the cathode reactor vessel (8) to the anode reactor vessel (4) during operation of the reactor device (2); wherein the anode reactor vessel (4) at least partially surrounds the cathode reactor vessel (8). Furthermore, the present disclosure relates to a conversion system (1) for converting powdered metal oxides, in particular metal oxides contained in regolith, to a metal powder and molecular oxygen (O2), the conversion system (1) comprising at least one corresponding reactor device (2).

First claim

What is claimed is:

1 . A reactor device for converting powdered metal oxides contained in regolith, to metal powder and molecular oxygen, the reactor device comprising:
a cathode reactor vessel providing a receiving space for the powdered metal oxides and adapted to be connected to an electron source such that the powdered electrode oxides can be converted to the metal powder and oxygen ions by the application of an electrical potential, and an anode reactor vessel adapted to be connected to an electron sink to attract the oxygen ions travelling through an electrolyte from the cathode reactor vessel to the anode reactor vessel during operation of the reactor device; wherein the anode reactor vessel at least partially surrounds the cathode reactor vessel.

2 . The reactor device according to claim 1 , wherein the cathode reactor vessel is at least partially received in the anode reactor vessel.

3 . The reactor device according to claim 1 , wherein the anode reactor vessel circumferentially encompasses the cathode reactor vessel.

4 . The reactor device according to claim 1 , wherein the anode reactor vessel at least partially holds the electrolyte.

5 . The reactor device according to claim 1 , wherein the anode reactor vessel contains the electrolyte.

6 . The reactor device according to claim 1 , wherein an anode reactor wall of the anode reactor vessel is at least partially permeable to allow a diffusion of oxygen ions through the anode reactor wall.

7 . The reactor device according to claim 1 , wherein the anode reactor vessel is at least partially formed of an oxygen ion conducting ceramic material to allow for a transfer of the oxygen ions towards an oxygen collecting reactor container located outside of the anode reactor vessel.

8 . The reactor device according to claim 1 , wherein at least a section of an anodic outer surface of the anode reactor vessel is covered by an anodic electrode connecting material.

9 . The reactor device according to claim 8 , wherein the anodic electrode connecting material is at least partially provided as paste applied to the anodic outer surface.

10 . The reactor device according to claim 9 , wherein the anodic electrode connecting material is at least partially provided as composite material composed of ceramic and metal materials.

11 . The reactor device according to claim 8 , wherein the anodic electrode connecting material is at least partially provided as a mesh.

12 . The reactor device according to claim 8 , wherein the anodic electrode connecting material is at least partially provided as bath.

13 . The reactor device according to claim 8 , wherein the bath contains molten metal.

14 . A conversion system for converting powdered metal oxides contained in regolith, to a metal powder and molecular oxygen, the conversion system comprising at least one reactor device comprising:
a cathode reactor vessel providing a receiving space for the powdered metal oxides and adapted to be connected to an electron source such that the powdered electrode oxides can be converted to the metal powder and oxygen ions by the application of an electrical potential, and an anode reactor vessel adapted to be connected to an electron sink to attract the oxygen ions travelling through an electrolyte from the cathode reactor vessel to the anode reactor vessel during operation of the reactor device; wherein the anode reactor vessel at least partially surrounds the cathode reactor vessel.

15 . The conversion system according to claim 14 , further comprising a powder cartridge configured to be inserted into the cathode reactor vessel and to hold the powdered metal oxides during conversion.
