Изобретение относится к катализаторам и способам получения оксидных катализаторов, применяемых в процессах глубокого окисления органических соединений и оксида углерода в газовых выбросах промышленных производств. Описанный катализатор включает оксиды хрома, меди, оксид алюминия, дополнительное соединение, промотор. 3 с. и 7 з.п.ф-лы, 2 табл., 1 ил.
FIELD: oxidation catalysts.
SUBSTANCE: alumina-based catalyst contains (on conversion to oxides) 2-15% chromium oxide, 2-15% copper oxide, at least one additional element selected from alkali and alkali-earth metals, silicon, iron, magnesium, titanium, zirconium, and cerium in amounts from 0.01 to 45% and 2 to 15% of promoter: at least one compound of metal from following group: magnesium, nickel, manganese, cobalt, iron, and vanadium. Catalyst preparation procedures: (1) chromium and copper compounds, aluminum hydroxide, additional compound, and promoter are mixed and resulting mixture is molded, dried, and calcined; (2) alumina carrier bearing and additional compound is impregnated with solution containing chromium and copper compounds and promoter, dried, and calcined.
EFFECT: enhanced catalytic activity in oxidation reactions, especially in presence of sulfur compounds, and increased mechanical strength.
