NSC technology removes NOX from a lean gas stream and converts it to N₂.

NO_X is adsorbed (lean) and then reduced (rich) → N₂.

The NSC can be regenerated thermally or under a rich condition. During lean operation, the NSC can also oxidise carbon monoxide (CO) and hydrocarbons (HC) in a similar fashion to that of a diesel oxidation catalyst (DOC).

Composition: Precious metals (Pd, Pt or Rh) with rare earth oxide (REO) and alumina oxide, coated on a flow-through monolith.

Our NO_X storage catalysts…

Store NO_X in low temperatures and lean conditions, and these storage properties can be tuned to suit individual vehicles and specific applications and systems
Have high durability against temperature, poisons and rich operation
Enable effective storage and reduction of NO_X, and efficient removal of CO and HC.
Can condition the ratio of NO:NO₂ for a downstream SCR device
Have superior activity and tuneable temperature windows.
