FIELD: catalytic chemistry; method of afterburning of organic admixtures and waste gases; chemical and petrochemical industries.
SUBSTANCE: proposed method is used for cleaning waste gases from styrene, toluene, isopropyl benzene, formaldehyde and oxidation products of higher fatty acids. Proposed method includes evacuation and impregnation of globular aluminosilicate zeolite-containing carrier; used as carrier is highly thermostable cracking catalyst to 100-% absorption by aqua solution of H2PtCl6 or PdCl2 at concentration of platinum or palladium of 0.4-0.8 g/l and volume ratio of impregnating solution to carrier of (0.6-0.08):1.0 of followed by sulfidizing with hydrogen sulfide and drying of catalyst. Proposed method makes it possible to clean waste gases from organic admixtures by 99.5-100%.
EFFECT: enhanced efficiency.
