  • 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.

  • Patent number: 8845877
    Abstract: A method for heterocycle catalyzed electrochemical reduction of a carbonyl compound is disclosed. The method generally includes steps (A) to (C). Step (A) may introduce the carbonyl compound into a solution of an electrolyte and a heterocycle 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 carbonyl compound to at least one aldehyde compound. Step (B) may vary which of the aldehyde compounds is produced by adjusting one or more of (i) a cathode material, (ii) the electrolyte, (iii) the heterocycle catalyst, (iv) a pH level and (v) an electrical potential. Step (C) may separate the aldehyde compounds from the solution.

  • Patent number: 8524066
    Abstract: Methods and systems for electrochemical production of urea are disclosed. A method may include, but is not limited to, steps (A) to (B). Step (A) may introduce carbon dioxide and NOx to a solution of an electrolyte and a heterocyclic catalyst in an 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 may reduce the carbon dioxide and the NOx into a first sub-product and a second sub-product, respectively. Step (B) may combine the first sub-product and the second sub-product to produce urea.

  • Patent number: 8500987
    Abstract: A method for purification of carbon dioxide from a mixture of gases is disclosed. The method generally includes steps (A) and (B). Step (A) may bubble the gases into a solution of an electrolyte and a catalyst in an electrochemical cell. The 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 one or more compounds. The anode may oxidize at least one of the compounds into the carbon dioxide. Step (B) may separate the carbon dioxide from the solution.

  • Publication number: 20040159544
    Abstract: PFSAs having CO tolerances greater than 500 ppm at temperatures above 100° C. are provided by decreasing the equivalent weight and thickness of the membrane and impregnating the membrane pores with an oxide, e.g., a hydrophilic siloxane polymer or TiO2. This was accomplished by either impregnating an extruded PFSA film via sol-gel processing of tetraethoxysilane, or by preparing a recast film, using solubilized PFSA and an oxide source.
