Selective Catalytic Reductioin DeNOx DeDioxin Honeycomb Catalyst
Selective catalytic reduction principle
The NOx reduction reaction takes place on the catalyst surface. Before entering the catalyst layer the ammonia is injected and mixed with flue gas:
4NO + 4NH3 + O2 → 4N2 + 6H2O NO + NO2 + 2NH3 → 2N2 + 3H2O 2NO2 + 4NH3 + O2 → 3N2 + 6H2O
DeNOx Honeycomb Catalyst Introduction
Honeycomb catalysts consist entirely of catalytically active materials (titanium dioxide, vanadium oxides, tungsten oxides) and commonly are used in low dust applications.
High specific surface area
High activity in low-dust flue gases
Variable pitch and length
Low-dust flue gas applications (<10g/M3)
Typical industrial applications:
It is widely used inthermal power plants, coal-fired power plants, waste incineration plants, steel plants, fertilizer plants, nitric acid plants, cement plants, petrochemical chemical plants and other all industrial which need to reduce the NOx emissions, also used in diesel engines tail gas treatment etc.
