Abstract

Способ включает проведение газа, содержащего NO и NO, через последовательность двух слоев катализатора, добавку восстановителя для NOи для NO между слоями катализатора в таком количестве, что, кроме NO, также восстанавливается предусмотренная доля NO. Условия реакции устанавливают так, что в первом слое катализатора происходит разложение содержащегося в газе NO на азот и кислород самое большее до 95% в расчете на содержание NO на входе в первый слой катализатора, и что во втором слое катализатора, кроме химического восстановления NO, происходит химическое восстановление NO, так что содержание NO в газе уменьшается по меньшей мере на 50% в расчете на содержание NO на входе во второй слой катализатора.
