Abstract RU 2108149 C1

FIELD: sorbents; gas treatment. SUBSTANCE: granules of metal-containing sorbent supplemented with copper, chromium, and silver are calcined at 800-850 C in superheated steam atmosphere and impregnated by potassium bichromate and triethylenediamine aqueous solution at ratio sorbents/potassium bichromate/triethylenediamine 1:(0.04-0.08):(0.004-0.008). Impregnated granules are aged for 1.5-1.8 h and thermally treated. Invention can be applied to treat industrial effluent gases or to protect, individually or collectively, respiratory organs. EFFECT: improved preparation procedure.
