Abstract

PURPOSE: To stably remove NOx in exhaust gas with high efficiency but without causing any clogging of a pipe by adding one or more of hydrazine, amine, urea and amide to the exhaust gas containing NOx and brought the gas into contact with a compound of a transition metal serving as the catalyst.
