World-Class Catalyst การผลิต
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 เทคโนโลยี Works
Selective Catalytic การลด (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
การฉีด 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
