CATALYST FOR EXTENSIVE OXIDATION OF ORGANICS AND CARBON MONOXIDE IN GAS EMISSIONS AND METHOD OF PREPARATION THEREOF (VERSIONS) Russian patent published in 2003 - IPC

Abstract RU 2199387 C1

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. 10 cl, 1 dwg, 2 tbl, 11 ex
