High Temperture Iron-Zeolite Selective Catalyst Reduction Catalyst
Product Description
1. Introuduction
1). SCR technology is a recation at use of the denitration catalyst at a
certain temperature(270-400 degree),that NOX in the flue gas mixed
with ammonia gas from the reducing agent supply the system after
the occurence of the selective catalytic reduction reaction of
nitrogen and water ,thereby reducing NOX emissions , and reducing
smoke pollution to the environment.
The chemical eauation for a selective catalytic reaction process is
:
4NO+4NH3+O2→4N2+6H2O 6NO2+8NH3→7N2+12H20
NO+NO2+2NH3→2N2+3H20
2). At present, commercial SCR catalyst basically to TiO2 for the
substrate to V2O5 as the main active ingredient in WO3, MoO3 for
anti-oxidation, anti-drug of auxiliary ingredients.
3). High performance honeycomb SCR Catalyst features
- High activity&NOX removal efficiency
- Low SO2 conversion rate
- Low NH3 slip
- Excellent resistance to posioning&abrasiom
- High durability &stability
- Small volume ,high specific surface area,economical and practical.
4). The Capacity of our Production of Honeycomb SCR Catalyst of our company is 8000m³/year
