Nitrogen Oxide Denitrification Catalyst for Power Station SCR Catalyst
Product Description
Thereby reducing NOx emissions, and reducing smoke pollution to the environment. SCR denitration technology has become the mainstream technology of flue gas denitrification in the world.
At present, the commercial SCR catalysts are basically using TiO2 as base material and V2O5 as the main active ingredient, with WO3 and MoO3 as anti-oxidation and anti-poisoning auxiliary components.
There are three types of SCR catalysts in the market, honeycomb catalyst, plate-types catalyst and corrugated catalyst. Commonly used is the honeycomb catalyst, plate-types catalyst. Honeycomb SCR catalyst is a porous honeycomb homogeneous product, its main backing material is TiO2, WO3, and V2O5and so on.
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). Based on self-rennovation ,Yuanchen Continues to seek comprehensive cooperation with well known enterprises of advanced technolgy from both home and abroad . the company has cooperated with EE&E,G&G, NE ,CCIC on the advanced SCR technology in rent years, while established stable relationships with famous EPDIS power construction companies and equipments manufacturers as well.
4).High performance honeycomb SCR Catalyst features
a: high activity&NOX removal efficiency
b: low SO2 conversion rate
c:low NH3 slip
d: excellent resistance to posioning&abrasiom
e : high durability &stability
f: small volume ,high specific surface area,economical and practical.
5). the Capacity of our Production of Honeycomb SCR Catalyst of our company is8000m³/year.
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.
