  • Patent number: 11131028
    Abstract: The present disclosure is a method and system for the reduction of carbon dioxide. The method may include receiving hydrogen gas at an anolyte region of an electrochemical cell including an anode, the anode including a gas diffusion electrode, receiving an anolyte feed at an anolyte region of the electrochemical cell, and receiving a catholyte feed including carbon dioxide and an alkali metal bicarbonate at a catholyte region of the electrochemical cell including a cathode. The method may include applying an electrical potential between the anode and cathode sufficient to reduce the carbon dioxide to at least one reduction product.

  • Publication number: 20170121831
    Abstract: The present disclosure is a method and system for production of carboxylic based chemicals. A method for producing at oxalic acid may include receiving an anolyte feed at an anolyte region of an electrochemical cell including an anode and receiving a catholyte feed including carbon dioxide and an alkali metal bicarbonate at a catholyte region of the electrochemical cell including a cathode. Method may include applying an electrical potential between the anode and cathode sufficient to reduce the carbon dioxide to at least one reduction product and converting the at least one reduction product and an alkali metal hydroxide to an alkali metal oxalate via a thermal reactor. The method may further include converting the alkali metal oxalate to oxalic acid at the electrochemical acidification electrolyzer. The method may further include the co-production of halogen products from the anolyte region of the electrochemical cell, by the oxidation of hydrogen halides used as an anolyte feed.

  • Patent number: 9090976
    Abstract: Methods and systems for electrochemical reduction of carbon dioxide using advanced aromatic amine heterocyclic catalysts are disclosed. A method for electrochemical reduction of carbon dioxide may include, but is not limited to, steps (A) to (C). Step (A) may introduce water to a first compartment of an electrochemical cell. The first compartment may include an anode. Step (B) may introduce carbon dioxide to a second compartment of the electrochemical cell. The second compartment may include a solution of an electrolyte, a catalyst, and a cathode. The catalyst may include at least two aromatic amine heterocycles that are at least one of (a) fused or (b) configured to become electronically conjugated upon one electron reduction. Step (C) may apply an electrical potential between the anode and the cathode in the electrochemical cell sufficient for the cathode to reduce the carbon dioxide to a product mixture.

  • Publication number: 20140183038
    Abstract: Methods and systems for capture of carbon dioxide and electrochemical conversion of the captured carbon dioxide to organic products are disclosed. A method may include, but is not limited to, steps (A) to (C). Step (A) may introduce a solvent to a first compartment of an electrochemical cell. Step (B) may capture carbon dioxide with at least one of guanidine, a guanidine derivative, pyrimidine, or a pyrimidine derivative to form a carbamic zwitterion. Step (C) may apply an electrical potential between an anode and a cathode sufficient for the cathode to reduce the carbamic zwitterion to a product mixture.
