CATALYST PREPARATION METHOD AND CATALYST Russian patent published in 2003 - IPC

Abstract RU 2202414 C1

FIELD: reduction-oxidation catalysts. SUBSTANCE: supported catalyst for selective reduction of nitrogen oxides is prepared by simultaneous separate spraying of aluminum hydroxide and aluminum metal, the former being thermally transformed into aluminum oxide. In addition, aluminum/silicon compound is sprayed onto support separately from aluminum metal and active metallic component is supplied. Nitrogen oxides are selectively degraded in the form of the above-prepared catalyst at temperatures above 400 C. EFFECT: enabled degradation of nitrogen oxide in the high-temperature region. 19 cl, 1 dwg
