FIELD: chemistry.
SUBSTANCE: invention relates to field of heterogenic catalysis, namely to catalyst for purification of exhaust industrial gases from volatile organic compounds, and can be used in chemical industry, for instance, for complete oxidation of exhaust gases of glyoxal production from admixtures of formaldehyde, ethylene glycol, carbon monoxide. Described is catalyst for purification of exhaust gases from volatile organic compounds, including cerium dioxide, manganese oxide, silver and carrier - mesoporous silica gel. Also described is method of obtaining catalyst, which includes impregnation of mesoporous silica gel with water solution containing manganese and cerium nitrates, then, after intermediate drying and thermal processing impregnation with ammonia solution of silver oxide with further final drying and thermal processing. Described is method of purification of exhaust gases, which contain volatile organic compounds, with application of said catalyst.
EFFECT: increased catalyst efficiency due to more uniform active silver component on carrier surface, elaboration of shorter method of obtaining catalyst for purification of exhaust gases, containing volatile organic compounds.
