  • Publication number: 20190270047
    Abstract: The present invention relates to a method for continuous removal of carbon dioxide, the method comprising the steps of: a) preparing an aqueous solution containing an amine-based compound and an acidic calcium compound; b) bringing a gas containing carbon dioxide to be treated into contact with the aqueous solution to prepare a calcium carbonate precipitate; and c) recovering the calcium carbonate and then adding a basic calcium compound to the residual aqueous solution, wherein after step c), step b) and step c) are repeatedly performed. The removal of carbon dioxide by the method of the present invention has advantages of requiring low energy and being capable of mineralizing and removing carbon dioxide at a fast rate without a separate time for induction.

  • Patent number: 9713790
    Abstract: Disclosed are a compound including an oxalate, a carbon dioxide absorbent including the same, a method of preparing the carbon dioxide absorbent and a method of removing carbon dioxide, which may overcome issues of high recycling energy and low absorptivity of a conventional carbon dioxide absorbent to considerably reduce recycling energy and absorb a greater amount of carbon dioxide per unit absorbent, so that a size of a carbon dioxide absorption tower may be reduced and a less amount of recycling energy may be used, contributing to a substantial decrease in device manufacture costs and management costs.

  • Patent number: 8840806
    Abstract: Provided is an absorbent for capturing carbon dioxide. The absorbent may include an amino acid with multiple amine groups and an alkali-metal hydroxide mixed with the amino acid and thus, may increase an absorption capacity for carbon dioxide. When a sterically hindered effect is induced to the amino acid with multiple amine groups, the absorption capacity for carbon dioxide may increase and heat of absorption reaction may decrease and thus, energy consumed for regeneration of an absorbent may be reduced. The absorbent for capturing carbon dioxide may include amino acid with multiple amine groups and the metal hydroxide, and may provide a functional group around the amine groups to cause an sterically hindered effect and thus, the absorption capacity for carbon dioxide and an carbon dioxide absorption rate may increase, and the capital cost for a carbon dioxide capturing process and an operating cost may be significantly reduced.

  • Publication number: 20130345046
    Abstract: Disclosed are a bifunctional catalyst for simultaneously removing nitrogen oxide and particulate matters, capable of decomposing nitrogen monoxide and generating nitrogen dioxide through oxidation of nitrogen monoxide, a composite catalyst including the catalyst for simultaneously removing nitrogen oxide and particulate matters used for an apparatus to decrease exhaust gas of diesel vehicles, and a method for preparation thereof. The catalyst and the composite catalyst can be used in a device for reducing exhaust gas contaminants mounted on a diesel vehicle and an exhaust gas purification system comprising the device.
