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