Solid carbon dioxide absorbent including amine or a compound thereof for use in the capturing process of dry carbon dioxide, and method for manufacturing same

Abstract:

The present invention relates to a method for manufacturing a carbon dioxide absorbent and to the absorbent manufactured by the method. The method comprises: (A) a step of preparing a slurry composition including a carrier composition containing a support, an inorganic binder, and a solvent; (B) a step of preparing solid particles by spray drying the thus-prepared slurry composition; (C) a step of manufacturing a carrier by dry calcining the thus-prepared solid particles; and (D) a step of receiving an amine compound into the pores of the thus-manufactured carrier. According to the absorbent of the present invention, an absorbing reaction and a regenerating reaction at a low temperature range (less than or equal to 100.degree. C. may be conducted, and therefore, the cost for capturing CO.sub.2 in a dry capturing process may be expected to decrease.
