METHOD OF PRODUCING CHEMICAL CARBON DIOXIDE ABSORBER Russian patent published in 2016 - IPC B01J20/04 B01J20/30 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing carbon dioxide absorbers. Method comprises preparation of an aqueous suspension of hydroxides of alkali and/or alkali-earth metals, applying suspension on a substrate made from porous material, moulding and drying. When preparing an aqueous suspension, a water-soluble polymer is added with weight ratio of hydroxides of polymer equal to (80-95)/(20-5), and weight content of water in suspension from 40 to 70 %. Application of suspension on a substrate and moulding of a chemical absorber is carried out repeated impregnation of substrate with suspension. Drying is performed after each impregnation of substrate until complete removal of water. After last drying obtained material is treated water or aqueous solution of alkali metals to moisture content 15-25 wt%.

EFFECT: invention improves performance of chemical absorber.
