Gas-treatment device including such a composition comprising a ferrierite/iron-type zeolite

The device comprises a substrate designed to be traversed by gas. The substrate has an internal structure that is adapted for forming a particulate filter (1) in the gas and has a catalytic composition constituted of ferrierite zeolite in the form of acid containing iron (0.3-2 mass%) deposited on t...

Beschreibung
Zusammenfassung:	The device comprises a substrate designed to be traversed by gas. The substrate has an internal structure that is adapted for forming a particulate filter (1) in the gas and has a catalytic composition constituted of ferrierite zeolite in the form of acid containing iron (0.3-2 mass%) deposited on the substrate. The catalytic composition is configured for performing chemical reaction such as reduction of nitrogen oxide. Independent claims are included for: (1) a system for treating gas; and (2) an internal combustion engine.
