Abstract

Der Erfindung liegt die Aufgabe zugrunde, einen Katalysator zur selektiven Zersetzung von N2O in einem Gemisch nitroser Gase zu schaffen, der im Temperaturbereich von 700 °C bis mindestens 1000 °C ohne Beeinträchtigung seiner Katalysatoraktivität einsetzbar sein soll. Diese Aufgabe wird dadurch gelöst, daß der Katalysator aus einem porösen keramischen Trägermaterial und einer katalytisch aktiven Phase besteht, wobei das Trägermaterial zu mindestens 95 Masse-% aus einer oder mehreren Erdalkaliverbindung(en) besteht. Der erfindungsgemäße Katalysator ist vorzugsweise bei der Herstellung von Salpetersäure anwendbar.
