Beschreibung
Zusammenfassung:	PURPOSE:To obtain a catalyst oxidizing nitrogen oxides of lower order contained in an exhaust gas into the oxides of higher order by supporting a specified cobalt oxide or oxide of copper or of manganese on an aluminium oxide carrier obtained by heating gamma-aluminium oxide. CONSTITUTION:Aluminium oxide obtd. by heating gamma-aluminium oxide at 1,150-1,550 deg.C is used as the catalyst carrier. The active ingredient consisting of >=75wt% cobalt oxide CoXOY, wherein Y/X
