  • Method for reducing exhaust carbon dioxide
    Patent number: 7550127
    Abstract: A method for effectively absorbing and removing CO2 in an exhaust gas generated during an industrial process for reducing the amount of CO2 that is exhausted into the atmosphere. The exhaust gas containing CO2 is blown into an agglomerate of solid particles containing CaO and/or Ca(OH)2 so that the CO2 is in contact with the agglomerate for fixing the CO2 in the exhaust gas as CaCO3, thereby reducing the CO2 concentration in the exhaust gas. Preferably, the solid particles contain water, and more preferably, the solid particles contain surface adhesive water.
    Type: Grant
    Filed: February 28, 2007
    Date of Patent: June 23, 2009
    Assignee: JFE Steel Corporation
    Inventors: Tatsuhito Takahashi, Tsuneo Isoo, Makoto Kato, Haruyoshi Tanabe

  • Underwater immersion block and method to produce the same
    Patent number: 6843843
    Abstract: It is an object of the invention to effectively absorb and remove CO2 in an exhaust gas generated during an industrial process for reducing an amount of exhausting CO2 into the atmospheric air. The exhaust gas containing CO2 is blown into the agglomerate of solid particles containing CaO and/or Ca(OH)2 to contact CO2 to the agglomerate for fixing CO2 in the exhaust gas as CaCO3, thereby to reduce the CO2 concentration in the exhaust gas. Preferably, the solid particles contain water, and more preferably, the solid particles contain surface adhesive water.
