 und der   Rückstand   weiter bis zur völligen Austreibung des Stickstoffdioxydes erhitzt. Die Masse wird schliesslich bis zu einer Korngrösse granuliert, die durch ein Sieb mit 64 Maschen pro Quadratzoll hindurchgeht, jedoch von einem Sieb mit 400 Maschen pro Quadratzoll zurückgehalten wird.   16. 5 g   des sogewonnenen Katalysators werden in eine für die Umwandlung von Ammoniak in Stickstoffoxyde geeignete Kammer gebracht und bei geeigneter Temperatur   (650-850 )   ein Luft-Ammoniakgasstrom der ca. 8-3 Volumprozente Ammoniak enthält, durchgeleitet. Es gelingt so bis zu   94%   des angewendeten Ammoniaks in Stickstoffoxyde zu verwandeln. 



   PATENT-ANSPRÜCHE :
1. Verfahren zur Herstellung von Stickstoffoxyden aus Ammoniak nach dem Kontaktverfahren, dadurch gekennzeichnet, dass ein Katalysator verwendet wird, der ein Kobaltoxyd und Aluminiumoxyd bzw. eine Verbindung eines Kobaltoxydes mit Aluminiumoxyd enthält.

 and the residue is heated further until the nitrogen dioxide is completely expelled. The mass is finally granulated to a grain size that passes through a sieve with 64 meshes per square inch, but is retained by a sieve with 400 meshes per square inch. 16. 5 g of the catalyst thus obtained are placed in a chamber suitable for converting ammonia into nitrogen oxides and, at a suitable temperature (650-850), an air-ammonia gas stream containing approx. 8-3 volume percent ammonia is passed through. In this way, it is possible to convert up to 94% of the ammonia used into nitrogen oxides.



   PATENT CLAIMS:
1. A process for the production of nitrogen oxides from ammonia by the contact process, characterized in that a catalyst is used which contains a cobalt oxide and aluminum oxide or a compound of a cobalt oxide with aluminum oxide.

EMI2.1 2. Production of a catalyst for the method according to claim 1, characterized in that a mixture of cobalt nitrate and aluminum nitrate is heated until the nitrogen dioxide is completely expelled.
