High-DeNOx Performance SCR Catalysts

The best washcoat solutions for each type of application.

The Dinex SCR catalysts are engineered to meet the demands of future emission standards. Our holistic design includes resilient Cu-SCR, Fe-SCR and Vanadate SCR catalysts and can be used for various applications. With our Fe/Cu-SCR formulation high NOx conversion even after harsh thermal aging will be achieved. The Vanadate SCR formulation offers exceptional resistance to Sulphur poisoning and high THC levels for close-coupled position in the ATS.

Dinex SCR concepts consists of:

Vanadate SCR with high Sulfur and THC tolerance and low N₂O as first SCR, DeNO_X adjusted to engine operation

• Thermal durability adapted to engine out temperature range • Excellent DeNOx performance in broad engine operation window

High thermal durable Fe/Cu-SCR concept for second SCR after DPF

• Significant investment and operation cost savings for low and high temperature applications

High Sulphur resistance and low N₂O formation

• Applicable for broad fuel quality specifications • No unwanted secondary emissions like N₂O

Dinex Low-NO_X Aftertreatment Solution Application Examples

On-Road - Light, Medium and Heavy Commercial

KSCR4.2LT at first SCR position as robust solution for high THC in regeneration modes and against Sulphur poisoning
KSCR4.2LT shows very low N₂O formation in the low temperature operation window
KSCR4.2C is used as second SCR after the DPF to keep N₂O formation low and with the use of NO₂ from the DOC it shows high DeNO_X activity
Combination with KSCR3.4 (Cu-SCR) on ASC

Off-Road - Construction & Agriculture

KSCR4.2LT or KSCR4.2C at first SCR position as robust solution for high THC in regeneration modes and against Sulphur poisoning
KSCR4.2LT/C show very low N₂O formation in the low temperature operation window
KSCR5/KSCR3.4 (Fe/Cu-SCR) as second SCR after the DPF to ensure high thermal durability for DPF active regeneration events. The Fe/Cu combination keeps N₂O formation low and with the use of NO₂ from the DOC the DeNO_X activity is at high level.
KSCR3.4 (Cu-SCR) is used on the ASC
