  • Patent number: 8409331
    Abstract: The invention relates to auxiliary systems ensuring functioning of alkaline fuel cell (AFC), in particular to a method and device for sorptive purification of air used in an AFC of carbon dioxide. In accordance with the invention, in the method for purifying air for a fuel cell, the starting air is passed through an adsorber with an adsorbent of carbon dioxide, then the adsorbent is regenerated. After utilization the adsorbent comprising hydrated oxides of transition metals is regenerated at a temperature of 60-120° C. by the air spent in the fuel cell.

  • Publication number: 20130047850
    Abstract: Effective synthesis gas purification is achieved by applying copper adsorbents which are resistant to the reduction by the components of the synthesis gas H2 and CO at normal operation conditions. The novel adsorbents are produced by admixing small amounts of an inorganic halide, such as NaCl, to the basic copper carbonate precursor followed by calcination at a temperature sufficient to decompose the carbonate. The introduction of the halide can be also achieved during the forming stage of adsorbent preparation. These reduction resistant copper oxides can be in the form of composites with alumina and are especially useful for purification of synthesis gas or gas streams containing hydrogen carbon monoxide or other reducing agents.

  • Patent number: 8343260
    Abstract: Fluorinated metal-organic frameworks (“FMOFs”) are capable of adsorbing and desorbing gases and molecules. The FMOFs can be arranged in a variety of configurations and have internal hollow channels and cavities. In the FMOFs, hydrogen atoms have been substituted completely or partially with fluorine atoms or fluorinated groups in each linking organic ligand. The FMOFs have high densities, leading to an enhanced volumetric capacity for gas storage.
