SCR DeNOx is designed for reducing Nitrogen oxides (NOx) in exhaust gas through conversion in Nitrogen (N2) and water (H2O). This process is named Selective Catalytic Reaction (SCR).

The reaction needs ammonia (NH3) as a reducing agent, a temperature high enough and a catalytic brick wall.

The catalyst uses a ceramic substrate. In SCR, ammonia is used as selective reductant in the presence of excess oxygen.
