SCR Selective Catalytic Reduction Catalyst

SCR system injects reducing agent (urea) into the tail gas pipe of diesel engine through a set of electronically controlled injection system

Aqueous solution), ammonia NH3 produced by hydrolysis of urea aqueous solution and NOx in tail gas are emitted in SCR catalyst

Generate a series of reduction reactions, generate N2 and discharge water. In order to avoid secondary pollution caused by excess ammonia NH3, the injection amount of reducing agent must be accurately controlled according to the operating conditions of the engine. The SCR system is mainly composed of a urea injection system that can communicate with the engine electronic control unit ECU in real time and an SCR catalyst; SCR urea injection system is mainly divided into air assisted injection and direct injection according to the organizational form of urea aqueous solution injection; The removal efficiency of SCR system for NOx in exhaust gas can reach more than 90%. However, when the exhaust temperature is too low (such as below 150 ℃), the removal efficiency of NOx is very low because the operating temperature of SCR catalyst is not reached.

Depending on the NO/NO₂ content in the exhaust gas, two important main SCR reactions are distinguished:

• Without NO₂: Standard SCR:
  
  4 NH₃ + 4 NO + O₂ → 4 N₂ + 6 H₂O
• With NO₂: Fast SCR:
  
  4 NH₃ + 2 NO + 2 NO₂ → 4 N₂ + 6 H₂O​
