High Quality SCR Denox Honeycomb Ceramic 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:
SCR denitration catalyst belongs to high-tech products, mainly for the efficient denitration power plant flue gas, waste incineration of nitric acid tail gas industry and nitric acid plant, nitrate plant, steel plant, chemical fertilizer plant and other industries.
Principle: the catalyst at a certain temperature (200--400 °C), using ammonia as the reducing agent,take the advantage of the reducing agent selective, preferentially react with industrial emissions of nitrogen oxide, NOx catalytic reduction to nitrogen and water which no environmental pollution, has accelerated the catalytic role, to eliminate the purpose of NOx.
