FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry, as well as for purifying anode gas of an alkaline fuel cell. The carbon dioxide absorbent is a eutectic mixture of potassium and sodium hydroxides deposited on granular porous oxides of calcium and/or magnesium. The method of removing carbon dioxide gas from a gas mixture involves passing the gas mixture through a CO2 scrubber which consists of a chemical-resistant outer casing fitted with a fixed layer of the absorbent described above.
EFFECT: more efficient purification of gas from CO2.
