Abstract: A regeneration reactor of a CO2 capture system is disclosed. According to an embodiment of the present invention, in the CO2 capture system comprising a capture reactor selectively adsorbing CO2 by bringing a CO2-containing gas supplied from the outside into contact with a solid adsorbent, and a regeneration reactor separating the adsorbed CO2 from the solid adsorbent adsorbed with the CO2, the regeneration reactor includes a chamber having an inverted truncated cone shape being widened toward an upper part and narrowed toward a lower part, such that a pressure in the regeneration reactor is constantly maintained through the whole part and accordingly, a flow velocity in the chamber can be constantly maintained.

Abstract: An apparatus for drying particles in a fluidized state includes a particle input segment into which wet particles are input, a drying segment having a multi-perforated plate dividing an inner space of the drying segment into an upper section and a lower section, a plurality of upper partition plates partitioning the upper section and positioned above the multi-perforated plate, a plurality of lower partition plates in the lower section respectively corresponding to the plurality of upper partition plates, a plurality of pairs of channel plates in the lower section that pass through the multi-perforated plate such that each pair of the plurality of pairs of channel plates are respectively arranged on opposite sides of respective ones of the plurality of upper partition plates and on opposite sides of respective ones of the plurality of lower partition plates; and a heated-air flow supply segment for supplying hot gas to the drying segment.
