ABSTRACT:
A process and apparatus for removing nitrogen oxides (NO.sub.x) from an exhaust gas by catalytic reduction in the presence of added ammonia in which at temperatures of up to 300.degree. C. the exhaust gas is mixed with the ammonia in such a way that their residence time together before contacting the catalyst is at most one second.
