摘要： Provided herein is an apparatus for absorbing, capturing, and desorbing CO2 using solid amines, the apparatus comprising: a catcher used for capturing CO2 in flue gas and comprising a treatment chamber and a delivery pipe for adsorption of CO2 in the flue gas by means of a spherical solid amine adsorbent, the bottom end of the delivery pipe being provided with a flue gas inlet, a first solid amine inlet, and an adsorbent inlet; a desorber for heating and desorbing CO2 adsorbed by the solid amine adsorbent; and a cooler for cooling the solid amine adsorbent from the desorber. Also provided is a method for absorbing, capturing and desorbing CO2 using solid amine. The present invention realizes continuous operation of capture and desorption and can be used for capturing CO2 in large-scale industrial flue gas.
