Product Description

Selective catalytic reduction (SCR) catalyst called SCR flue gas denitration catalyst, SCR technology is denitration catalyst in the appropriate temperature, using ammonia (NH3) as the reducing agent, take the advantage of the reducing agent selective, preferentially reaction with industrial flue gas of nitrogen oxide(NOX), NOX is converted into no pollution of nitrogen and water, and NOx reduction efficiency is as high as above 90%. 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, V2O5 and so on.

1: Applicable Pollutants: Nitrogen Oxides ( NOx )

2: Applicable Source Type: Point

3: Typical Industrial Applications: 
Stationary fossil fuel combustion units such as electrical utility boilers,
industrial boilers, process heaters, gas turbines, and reciprocating internal combustion engines. In addition, SCR has been applied to nitric acid plants.

4: Achievable Emission: SCR is capable of NOx reduction efficiencies in the range of
85% to 95 %. Higher reductions are possible but generally are not cost-effective.

5:Advantages:
Higher NOx reductions than low-NOx burners and Selective Non-Catalytic Reduction (SNCR)
Applicable to sources with low NOx concentrations Reactions occur within a lower and
broader temperature range than SNCR.Does not require modifications to the
combustion unit

6:Reaction:
4NO+4NH3+O2→4N2+6H2O 2NO2+4NH3+O2→3N2+6H2O 

7: Technical Data:
vDimension: width:150mm×150mm,length from 300~1350mm;
warp pressure resistance bigger than 0.8Mpa, weft pressure resistance bigger
than 2.82MPa;
vSO2/SO3 reduction less than 0.9%;
vox efficiency of more than 92%;
vNH3 escape rate within 2ppm;
mechanical longevity can be as long as 9 years
