What is a denitrification catalyst? How does a denitrification catalyst work?

Denitrification catalysts are mainly based on TiO2 as carriers, and WO3 and MoO3 as antioxidant and anti-poisoning auxiliary components. In the SCR reaction, the denitrification catalyst is a substance that can cause the reducing agent to selectively react with nitrogen oxides in the flue gas at a certain temperature. The composition and proportion of the SCR catalyst vary according to the content of the components in the flue gas and the guaranteed value of the denitrification performance. TiO2: As a carrier of the catalyst, it provides a large specific surface area and highly selective active sites WO3: As a catalyst promoter, it improves the thermal stability of the catalyst, inhibits and delays the high-temperature sintering of the catalyst; inhibits sulfur conversion V2O5: As the most important active substance of the catalyst, it degrades NOX SCR is a selective catalytic reduction technology. This technology has the advantages of no by-products, no secondary pollution, simple device structure, removal efficiency of more than 90%, reliable operation and convenient maintenance, and is widely used in denitrification projects.
