SCR DeNOx catalysts as coated or solid extrudate
Selective catalytic reduction systems (SCR or DeNOx) function by the chemical reduction of NOx (NO and NO2) to nitrogen (N2) using ammonia. We offer coated
Vanadium catalysts, particularly those based on vanadium pentoxide (V₂O₅), are used in various industrial processes. Their areas of application include the selective catalytic reduction (SCR) of nitrogen oxides in exhaust gases as well as sulfuric acid production. This versatile utility is based on the chemical properties of vanadium pentoxide, which acts as an oxidizing agent.
In SCR systems, V₂O₅ is frequently used in combination with tungsten trioxide (WO₃) and titanium dioxide (TiO₂). These catalyst systems enable the conversion of nitrogen oxides into nitrogen and water and are utilized both in industrial plants and in exhaust gas aftertreatment. In this setup, titanium dioxide provides thermal stability, while tungsten trioxide supports performance at higher temperatures.
Another area of application is sulfuric acid production. In the contact process, vanadium pentoxide catalyzes the conversion of sulfur dioxide (SO₂) to sulfur trioxide (SO₃), thereby contributing to the production of sulfuric acid.
