Claims (13)
1. Katalysatorer til ammoniakoxidation dannet af en eller flere katalytiske enheder, hvoraf hver af dem er dannet af et par af blokke, der har en honey-comb-struktur og omfatter en ammoniakoxidationskatalysator, hvor hver af blokkene har en højde på mindre end 15 cm og mere end 2 cm, og der imellem dem er placeret et lag, som udfører den funktion, at det blander reagensgasstrømmen ensartet, med en højde på mere end 0,5 cm og ikke mere end 3 cm, dannet af skummateriale med åbne, vilkårligt forbundne celler.
2. Katalysatorenhed ifølge krav 1, hvor det mellemliggende skumlag har en højde på 0,5-2 cm.
3. Katalysatorenhed ifølge krav 1 eller 2, hvor højden af hver af blokkene er fra 2 til 6 cm.
4. Katalysatorenhed ifølge et af kravene 1 til 3, hvor massefylden af cellerne i honeycomb-blokkene ligger i området fra 3 til 10 celler/cm, og massefylden af porerne i skummaterialet er fra 4 til 20 porer/cm.
5. Katalysatorenhed ifølge et af kravene 1 til 4, hvor blokkene er dannet af keramisk eller metallisk materiale.

8. Katalysatorenhed ifølge et af kravene 1 til 7, hvor skumlaget er dannet af opskummet aluminium.
9. Katalysatorenhed ifølge krav 1 til 8, hvor ammoniakoxidationskatalysatoren foreligger i form af en coating opnået ved at dyppe blokkene i en opslæmning indeholdende gamma-aluminium med en på denne aflejret katalysator af blandede oxider med en sammensætning udtrykt i vægtprocent af CoO, MnO og sjældne jordartsmetaller i det laveste valensstadium på 20-45 % CoO, 50-60 % MnO og 0,5-20 % oxider af sjældne jordartsmetaller, fjerne blokkene fra opslæmningen og kalcinere dem.
10. Katalysatorenhed ifølge krav 7, hvor det sjældne jordartsmetaloxid er La203 og blandinger deraf med Ce02.
11. Katalysatorenhed ifølge krav 7, hvor den katalysatorcoating, der er til stede på blokkene, omfatter 0,001 -1 vægtprocent Pt.
12. Fremgangsmåde til ammoniakoxidation, hvor den anvendte katalysator er dannet af en eller flere katalysatorenheder ifølge et af kravene 1 til 8.
