Abstract

Применение катализатора для разложения NO в условиях способа Оствальда при температурах от 750 °С до 1000 °С и давлении 0,9-15 бар, причем катализатор содержит носитель, выбранный среди альфа-АlОи ZrO, и нанесенное на носитель покрытие из родия или оксида родия, или смешанного Pd-Rh катализатора. Устройство для разложения NO в условиях осуществления способа Оствальда содержит, по меньшей мере, один катализатор, установленный после катализаторных сеток в направлении потока для окисления NH. Использование изобретения обеспечивает повышение эффективности процесса за счет высокой активности катализатора.
