Beschreibung
Zusammenfassung:A catalyst for oxidation of ammonia is of the general formula (AxByO3z)k (MEmOn)f, wherein: A is a cation of Ca, Sr, Ba, Mg, Be, La or mixtures thereof, B is cations of Mn, Fe, Ni, Co, Cr, Cu, V or mixtures thereof, x=0-2, y=1-2, z=0.8-1.7; MemOn is an aluminum oxide and/or oxide of silicon zirconium, chromium, aluminosilicates, oxides of rare earth elements (REE) or mixtures thereof, m=1-3, n=1-2, k and f are % by weight, with the ratio f/k=0.01-1. The catalyst may be granules of different configuration, including blocks of honeycomb structure. The catalyst is thermally stable, resistant to thermal shocks. There is no water runoff.
