FIELD: methods of separation of gases. SUBSTANCE: alumina, silicon dioxide or titanium dioxide are used as carriers for a coating of absorbent applied on them. The composition of absorbent is as follows (percent of mass): tin or tin oxides, or their combination (0.22-24), stabilizing component of the group: copper, nickel, cobalt, iron or their oxides (0.025-2.9), carrier (73.1-99.7). Regeneration of the exhaust absorbent is carried out at 300-600 C. EFFECT: higher efficiency. 3 cl, 3 tbl
