SCR Honeycomb Denitrification Catalyst
Industrie-leading honeycomb SCR catalysts engineered for superior NOx removal across power and non-power sectors. Annuel production capacity of 10,000 m³ backed by Sino-Korean technical expertise.
World-Class Catalyst Fabrication
Do Sender Chem is a specialized environmental technology company and Sino-Korean joint venture, dedicated to the research, development and production of honeycomb SCR denitrification catalysts.
How SCR Technologie Works
Selective Catalytic Réduction (SCR) converts nitrogen oxides (NOx) into harmless nitrogen (N₂) and water (H₂O) using ammonia as the reducing agent in the presence of our high-performance catalyst.
Flue Gas Inlet
NOx-laden flue gas enters the SCR reactor at optimal temperature
Injection d'NH₃
Ammonia is precisely injected and mixed with the flue gas
Catalytic Reaction
NOx + NH₃ → N₂ + H₂O over the honeycomb catalyst surface
Clean Emission
Purified gas exits the stack — no secondary pollution
