Selective catalyst reduction
WebSelective catalytic reduction (SCR) systems are post-combustion active emission control technology systems. The system uses a catalyst bed and an injected liquid-reductant agent to scavenge pollutants, nitrogen oxides (NOx), and produce diatomic nitrogen (N2) and water vapor (H2O).
