CARBON DIOXIDE ABSORBER AND A METHOD FOR REMOVING CARBON DIOXIDE FOR GAS MIXTURES Russian patent published in 2005 - IPC

Abstract RU 2244586 C1

FIELD: gas treatment.

SUBSTANCE: invention relates to adsorption separation of gases and provides carbon dioxide absorbent, which is prepared by impregnating porous alumina with potassium carbonate, alumina having been preliminarily treated with alkali solution, in particular solution of alkali metal hydroxides and/or carbonates. Alkali treatment is carried out at temperature above 40^оС. Method of removing carbon dioxide from gas mixture, including adsorption separation of carbon dioxide from atmospheric air in cyclic processes under thermal regeneration or short-cycle heating-free adsorption conditions, is characterized by that process is conducted at 20 to 200^оС with above indicated absorber.

EFFECT: increased dynamic capacity of absorber and increased carbon dioxide absorption velocity.
