Abstract

En katalysatorpatronenhet for ammoniakkoksidasjon omfatter et par av tilbakeholdende nett i en avstand fra hverandre på mindre enn 50mm som definerer en innelukning fylt med en tilfeldig pakket masse av partikler av en sammensetning omfattende oksider av minst ett metall valgt fra mangan, jern, nikkel og kobolt, spesielt kobolt og minst element A valgt fra sjeldne jordarts- metaller og yttrium i slike andeler at atomforholdet mellom element A og kobolt er i område fra 0,8 til 1,2. Katalysatorpartiklene har en minimumdimen- sjon på minst 0,5mm og en maksimumdimensjon på ikke mer enn 5mm, og avstanden mellom nettene er minst 4 x, men ikke mer enn 50 x, maksimum- dimensjonen av partiklene. Enheten kan strekke seg over tverrsnittet av ammoniakkoksidasjonsreaktoren eller en katalysatorpatron kan omfatte et gitter eller en gjennomhullet plate, som strekker seg over tverrsnittet av reaktoren, med en enhet som nevnt i hver apertur.
