US Patent 7550127 Method for reducing exhaust carbon dioxide

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.
