  • Publication number: 20230053646
    Abstract: The disclosure provides a photodegradant for carbamazepine, a method and an apparatus for degrading carbamazepine, and relates to the technical filed of degradation of organic pollutants. The photodegradant provided by the disclosure includes a composite solution of a persulfate and a sulfite. In the disclosure, ultraviolet (UV), the persulfate (PS) and the sulfite (S(IV)) are combined to degrade carbamazepine, during which hydrogen sulfate (HSO3?) generated by the hydrolysis of sulfite in water participates in the reaction to produce a large amount of SO4?? and HO?, thus improving the degradation rate and degradation efficiency of carbamazepine. The composite advanced oxidation system, i.e., the ultraviolet/persulfate/sulfite (UV/PS/S(IV)) system, provided by the disclosure has stronger oxidizability than the ultraviolet/persulfate (UV/PS) system and the ultraviolet/sulfite (UV/S(IV)) system, and results in high degradation rate and high degradation efficiency of carbamazepine.

  • Patent number: 8563183
    Abstract: An integrated dry gas fuel cell (IDG-FC) is provided. The IDG-FC includes at least one solid oxide fuel cell having an anode, a cathode and an electrolyte membrane disposed between the anode and the cathode. The IDG-FC further includes a conversion bed, where carbon dioxide gas is provided to the conversion bed to convert carbon monoxide gas from the carbon dioxide gas. Solid carbonaceous fuel is provided to the conversion bed to promote the gas conversion. The carbon monoxide is provided as fuel to the anode, and air is supplied to the cathode to provide oxygen for oxidation of the carbon monoxide at the anode to generate electric power. This new process does not require water, and supplies the oxygen required for the oxidation reaction through an ionically selective solid oxide electrolyte membrane.

  • Patent number: 8465857
    Abstract: A proton exchange membrane comprises a hybrid inorganic-organic polymer that includes implanted metal cations. Acid groups are bound to the hybrid inorganic-organic polymer through an interaction with the implanted metal cations. An example process for manufacturing a proton exchange membrane includes sol-gel polymerization of silane precursors in a medium containing the metal cations, followed by exposure of the metal-implanted hybrid inorganic-organic polymer to an acid compound.
