Abstract
The present disclosure relates to a system for carbon dioxide separation. The system includes a conducting membrane having two phases. The first phase is a solid oxide porous substrate. The second phase is molten carbonate. The second phase is positioned within the solid oxide porous substrate of the first phase. The system also includes a H2 and CO2 gas input stream separated from a CH4 gas input stream by the conducting membrane. The CO2 is removed from the H2 and CO2 gas input stream as it contacts the membrane resulting in a H2 gas output stream from the H2 and CO2 gas input stream and a CO and H2 gas output stream from the CH4 gas input stream.

A system for carbon dioxide separation comprising:
- a conducting membrane comprising two phases, the first phase comprising a solid oxide porous substrate, the second phase comprising molten carbonate, wherein the second phase is positioned within the solid oxide porous substrate of the first phase;
- and
- a H2 and CO2 gas input stream separated from a CH4 gas input stream by the conducting membrane, wherein the CO2 is removed from the H2 and CO2 gas input stream as it contacts the membrane resulting in a H2 gas output stream from the H2 and CO2 gas input stream and a CO and H2 gas output stream from the CH4 gas input stream.
A system for carbon dioxide separation comprising:
- a conducting membrane comprising two phases, the first phase comprising a solid oxide porous substrate, the second phase comprising molten carbonate, wherein the second phase is positioned within the solid oxide porous substrate of the first phase;
- water-gas shift reactor;
- and
- a H2 and CO2 gas input stream separated from a CH4 gas input stream by the conducting membrane, wherein the CO2 is removed from the gas input stream as it contacts the membrane resulting in a H2 gas output stream from the H2 and CO2 gas input stream and a CO and H2 gas output stream from the CH4 gas input stream, and wherein the CO and H2 gas output stream contact the water-gas-shift reactor to form a H2 and CO2 gas output stream.
A method of carbon dioxide separation comprising:
- contacting a H2 and CO2 gas input stream with a conducting membrane comprising two phases, the first phase comprising a solid oxide porous substrate, the second phase is positioned within the solid oxide porous substrate of the first phase and comprises molten carbonate;
- and
- utilizing the conducting membrane to separate the H2 and CO2 gas input stream from a CH4 gas input stream, wherein the CO2 is removed from the H2 and CO2 gas input stream as it contacts the membrane resulting in a H2 gas output stream from the H2 and CO2 gas input stream and a CO and H2 gas output stream from the CH4 gas input stream.
