    Abstract: Systems and methods are described that utilize mixed conductive membranes in conjunction with solid oxide electrolysis in a single unit operation. The mixed conductive membranes of the systems are high-flux electrochemical separation membranes that can selectively and efficiently capture CO2 from a source gas, e.g., a flue gas or fuel gas, by transporting the CO2 across the membrane in the form of carbonate ions followed by oxidation of the carbonate-ions at the second side of the membrane to reform CO2 in a capture stream. The solid oxide electrolysis can be immediately downstream of the capture system to convert the CO2 into CO and H2O into H2, for example thereby forming syngas thereby capturing CO2 and converting it to a more useful form.

    Abstract: A NaSICON cell is used to convert carbon dioxide into a usable, valuable product. In general, this reaction occurs at the cathode where electrons are used to reduce the carbon dioxide, in the presence of water and/or hydrogen gas, to form formate, methane, ethylene, other hydrocarbons and/or other chemicals. The particular chemical that is formed depends upon the reaction conditions, the voltage applied, etc.

  • Patent number: 8647497
    Abstract: A system for hydrogen sulfide removal from a sour gas mixture including hydrogen sulfide. The sour gas mixture is reacted with a transition metal compound in a scrubber. Sulfide from the hydrogen sulfide is oxidized to form elemental sulfur and the transition metal is reduced to form a reduced state transition metal compound. An electrochemical redox reaction is performed including the reduced state transition metal compound to regenerate the transition metal compound in an electrolyzer including a power source. During the electrochemical redox reaction a voltage from the power source applied to the electrolyzer is controlled to regenerate the transition metal compound at a rate sufficient to match a flow rate of hydrogen sulfide into the scrubber or maintain a predetermined maximum hydrogen sulfide level out from the scrubber. The transition metal compound regenerated is returned to the scrubber for the reacting.
