Jul 19, 2022

The main component of commercial SCR denitrification catalysts is vanadium-tungsten-titanium oxide. Among them, TiO2 is the carrier, WO3 is the co-catalyst, V2O5 is the active component of the catalyst, usually using urea or ammonia as the reducing agent, the main denitrification chemical reaction with ammonia as the reducing agent is:


4NO + 4NH3 + O2 → 4N2 + 6H2O(1)
2NO2+4NH3+O2→3N2+6H2O(2)
NO2+NO+2NH3→2N2+3H2O(3)
