Elimination of nitrogen oxides from exhaust gases with ...

What is claimed is: 1. A method of removing nitrogen oxides from an exhaust gas containing them which comprises contacting the exhaust gas with a nitrile compound in the presence of oxygen at a temperature of about 500° to about 1000° C and a residence time of more than about 0.1 second without using a solid catalyst to decompose the nitrogen oxides and the nitrile compound into harmless ...
