FIELD: chemistry.
SUBSTANCE: method consists in simultaneous sorption and oxidation -recovery of gases by means of sequentially passing them through a bed of sorption glauconite-based catalyst. Wherein the catalyst is prepared as follows: enriched highly-dispersed glauconite is mixed with intercalated graphite, the resulting mixture is modified with the galvanic sludges solution containing heavy metal compounds, and afterwards the resulting mass is granulated and fired at the temperature of 600-700°C for 1-1.5 hours.
EFFECT: increased efficiency of gas emissions cleaning, and also allows to expand the thermal cleaning mode.
