  • Patent number: 11339996
    Abstract: An electrochemical compressor utilizes an anion conducting layer disposed between an anode and a cathode for transporting a working fluid. The working fluid may include carbon dioxide that is dissolved in water and is partially converted to carbonic acid that is equilibrium with bicarbonate anion. An electrical potential across the anode and cathode creates a pH gradient that drives the bicarbonate anion across the anion conducting layer to the cathode, wherein it is reformed into carbon dioxide. Therefore, carbon dioxide is pumped across the anion conducting layer. The compressor may be part of a refrigeration system that pumps the working fluid in a closed loop through a condenser and an evaporator.

  • Publication number: 20140251822
    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.

  • Publication number: 20140238871
    Abstract: A method for electrochemical production of synthesis gas from carbon dioxide is disclosed. The method generally includes steps (A) to (C). Step (A) may bubble the carbon dioxide into a solution of an electrolyte and a catalyst in a divided electrochemical cell. The divided electrochemical cell may include an anode in a first cell compartment and a cathode in a second cell compartment. The cathode generally reduces the carbon dioxide into a plurality of components. Step (B) may establish a molar ratio of the components in the synthesis gas by adjusting at least one of (i) a cathode material and (ii) a surface morphology of the cathode. Step (C) may separate the synthesis gas from the solution.

  • Publication number: 20140216944
    Abstract: A graphite oxide or graphene preparation method includes providing a plasma electrolytic apparatus, where an electrolytic solution is provided and a graphite electrode is configured as a cathode of the plasma electrolytic apparatus; and providing a cathodic current so as to initiate a plasma electrolytic process at the graphite cathode to obtain graphite oxide or graphene. The graphite oxide can be synthesized through plasma electrolytic processing at relatively low temperature under atmospheric pressure within a very short period of time, without the need for concentrated acids or strong oxidizing agents. The present invention may prepare graphite oxide with plasma electrolytic process directly from graphite, without requiring any prior purification. This plasma electrolytic process of the present invention is quite promising and provided with advantages such as low cost, simple setup, high efficiency, and environmental friendliness.

  • Publication number: 20140202874
    Abstract: The embodiments herein relate to methods and apparatus for forming graphitic material from a carbon oxide feedstock in an electroplating chamber containing molten inorganic carbonate as electrolyte. Carbon dioxide flows into a reaction chamber containing one or more cathodes, one or more anodes, and a molten carbonate electrolyte. The carbon dioxide and/or carbonate reduces at the cathode to form graphitic material, which may be removed from the surface of the cathode through various mechanisms. The graphitic material is then separated out from the electrolyte.
