Double-effect catalyst for denitrification and decarbonization

Introduction of double-effect catalyst for removal of CO-NOX

The double-effect catalyst for denitrification and decarbonization (also known as CO-NOx purification catalyst) is prepared by coupling the unique transition metal oxides and precious metal active components with composite titanium as the carrier. It has a unique catalytic purification function for CO and NOx pollutants, and can decompose CO while removing NOx. With the technical characteristics of strong purification performance, wide operating temperature range and long service life, etc., the catalyst is widely used in flue gas treatment of industrial kilns in industries of iron and steel sintering, coking, sodium carbonate, lime kiln and alumina kiln.

Principle of CO-NOx removal

Both decarbonization and denitrification reactions with catalysts are typical gas-solid catalytic reactions. At a certain temperature, the catalyst adsorbs carbon monoxide, nitrogen oxides and oxygen in flue gas, and then chemically reacts on the surface of the catalyst for complete oxidation, during which harmless carbon dioxide is generated and a lot of heat is released. The generated heat can also be reused according to the situation, so as to realize emission reduction and energy conservation.
