Abstract
A találmány tárgya eljárás gázokban dinitrogén-oxid (N2O)mennyiségének csökkentésére, amely gázok még NO nitrogén-oxidokat ésvizet tartalmaznak oly módon, hogy a gázt egy katalizátor ágyonvezetik keresztül 700-900 °C hőmérsékleten, amely katalizátoralumínium-oxid vagy cirkónium-oxid tűzálló anyagok közül választottszemcseközti porozitással rendelkező granulátumokból áll.
