SCR/ASC Diesel Catalyst 157mm

SCR system
Function: Selective catalytic reduction, using urea to convert NOx into N₂ and H₂O
Features: NOx is reduced by more than 90%, urea injection system is required, working temperature is 250-450℃
Substrate: Vanadium-based or copper-based molecular sieve

SCR+ASC system（PT coating at the rear 2-3in）
Function: Add ammonia slip catalyst on the basis of SCR
Features: Double purification of NOx+NH₃, more complex system
Substrate: SCR section: Vanadium-based/Copper-based, ASC section: Copper-based/Zeolite

ASC system
Function: Ammonia slip catalyst, oxidizing NH₃ to N₂ and H₂O
Features: Need to be used with SCR, working temperature is above 150℃
Substrate: Copper-based molecular sieve or platinum metal

Vanadium-based molecular sieve-Euro 5
Active ingredients: V₂O₅/WO₃/TiO₂
Applicable scenarios: traditional SCR system
Advantages: good high temperature stability, strong sulfur resistance
Disadvantages: poor low temperature activity

Copper-based molecular sieve Euro6 (Euro6 commonly used molecular sieve)
Active ingredients: Cu/zeolite
Applicable scenarios: Euro6 commonly used
Advantages: good low temperature activity, non-toxic
Disadvantages: easy to sinter at high temperature

Iron-based molecular sieve-Euro6
Active ingredients: Fe/zeolite
Applicable scenarios: high temperature SCR system
Advantages: high temperature resistance, low cost
Disadvantages: sensitive to water
