<p>A method for manufacturing a solid carbon dioxide absorbent comprises the steps of: manufacturing papers by mixing 10-80 wt% of a fiber material capable of enduring at over 100°C, 10-80 wt% of a porous inorganic material, and 5-20 wt% of inorganic/organic binder; manufacturing a cylindrical honeycomb molded body by molding the papers in a polarization molded body then winding it; dipping the honeycomb molded body in a solution in which a carbon dioxide absorbing material is dissolved, then drying it; and hardening the honeycomb molded body dipped with the carbon dioxide absorbing material and cooling it. The solid carbon dioxide absorbent manufactured by the method does not generate a breaking phenomenon of the absorbent or a process pressure descent due to the air flow during the removal of carbon dioxide from exhaust gas, does not require a regular filling or filtering of concentrated carbon dioxide, and can realize a stable dry process of absorbing, separating and concentrating carbon dioxide with reduced operating cost and facility cost through process simplification. [Reference numerals] (AA) ceramic paper(comprising ceramic fiber, porous inorganic, binder);(BB) molding in cylindrical honeycomb having cross section with holes by molding a side in wave shape and winding;(CC) dipping absorbent in solution(K2CO3 or Na2CO3 or CaCO3, Amine);(DD) drying, 100-120°C;(EE) plasticizing, 450-600°C</p> |
