Abstract

Описывается способ уменьшения содержания NOи NO в газах при использовании газообразного восстановителя, применяемого в количестве, необходимом для восстановления NO, в присутствии одного или нескольких цеолитов, нагруженных железом, с кристаллической структурой, не имеющей пор или каналов величиной более 7 ангстрем, и при температуре менее 450°C в реакционной зоне. При этом скорость потока газовой смеси и/или количество катализатора выбирают так, что достигается желательная степень разложения NO. Способ можно использовать особенно в производстве азотной кислоты, на электростанциях и газовых турбинах.Международная заявка была опубликована вместе с отчетом о международном поиске.
