Abstract

Abstract Process for reducing nitrogen oxides in gas mixtures comprises feeding compounds which release NH3 by catalytic hydrolysis into the gas mixtures. The compounds are introduced in the vapour state. Also claimed is an apparatus for carrying out the process comprising a catalyst (26, 30) arranged between an inlet and outlet of the gas mixture in the direction of flow, and a device (24) for providing the above compounds. Preferably urea or reaction product of urea is used as the compound releasing NH3 by catalytic hydrolysis. Urea is vaporised from the solid state, preferably using an intensive light source.
