METHOD OF PRODUCING CHEMICAL CARBON DIOXIDE ABSORBER Russian patent published in 2017 - IPC B01J20/04 B01J20/30 

FIELD: chemistry.

SUBSTANCE: invention relates to production of chemical carbon dioxide absorber, used in individual breathing apparatus. Method of producing chemical carbon dioxide absorber consists in preparing a suspension of hydroxides of alkali and/or alkali-earth metals by water dissolution of alkali metal hydroxides with subsequent addition of hydroxides of alkali and/or alkali-earth metals. Method includes adding to suspension after dissolving alkali metal hydroxides a modifying agent in form of halides of alkali and/or alkali-earth metals or their mixture in amount of 1–3 %. Suspension is treated with a substrate of fibre material, followed by moulding and drying.

EFFECT: obtained absorber has high mechanical strength and good kinetics of carbon dioxide absorption.
