SCR denitration catalyst

It is the core component of selective reduction catalysis technology. The raw flue gas from the kiln/boiler is first mixed with ammonia gas at 150-420 ℃, and then evenly distributed through flow guidance and rectification. Then, it passes through a honeycomb type denitrification catalyst, and the mixed flue gas undergoes catalytic reaction on the catalyst surface to generate clean nitrogen gas and water. Finally, it is discharged or enters the next unit. And SCR denitrification catalysts have small volume, large specific surface area, and high activity; Featuring high denitrification efficiency, the monomer adopts front-end hardening technology and is resistant to erosion; Suitable for a wide temperature range of 150 ℃ -420 ℃, widely used in industries such as steel, waste incineration power generation, gas heating boilers, papermaking, acid washing, cement, lime, non-ferrous metallurgy, ships, diesel engines, gas turbines, etc.

Reaction mechanism

The raw flue gas from the kiln/boiler is first mixed with ammonia at 150-420 ℃. After being guided and rectified, the flue gas is evenly distributed. Then, it passes through a honeycomb type denitrification catalyst, and the mixed flue gas undergoes catalytic reaction on the catalyst surface to generate clean nitrogen gas and water. Finally, it is discharged or enters the next unit.
