  • CARBON DIOXIDE ABSORBING COMPOSITION INCLUDING ANTISOLVENT, AND METHOD AND APPARATUS FOR ABSORBING CARBON DIOXIDE USING THE SAME
    Publication number: 20150290581
    Abstract: This invention relates to a carbon dioxide absorbing composition including an antisolvent, and to a method and apparatus for absorbing and regenerating carbon dioxide using the same, wherein in a process and apparatus for absorbing carbon dioxide from a gas mixture including carbon dioxide such as a flue gas of a coal-fired power plant and separating a bicarbonate slurry including a large amount of carbon dioxide so as to be regenerated at high pressure, a bicarbonate slurry production yield can be increased to thereby reduce the cost for sensible heat, latent heat and regeneration energy necessary for regeneration, cooling and heating of the carbon dioxide absorbing solution.

  • Graphene composite nanofiber and preparation method thereof
    Patent number: 8519045
    Abstract: Disclosed are a graphene composite nanofiber and a preparation method thereof. The graphene composite nanofiber is produced by dispersing graphenes to at least one of a surface and inside of a polymer nanofiber or a carbon nanofiber having a diameter of 1˜1000 nm, and the graphenes include at least one type of monolayer graphenes, and multilayer graphenes having a thickness of 10 nm or less. The graphene composite nanofiber can be applied to various industrial fields, e.g., a light emitting display, a micro resonator, a transistor, a sensor, a transparent electrode, a fuel cell, a solar cell, a secondary cell, and a composite material, owing to a unique structure and property of graphene.
