COMPOSITION CATALYTIQUE ET DISPOSITIF DE TRAITEMENT DES GAZ COMPRENANT UNE TELLE COMPOSITION

摘要

#CMT# #/CMT# 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. #CMT# : #/CMT# Independent claims are included for: (1) a system for treating gas; and (2) an internal combustion engine. #CMT#USE : #/CMT# The device is useful in a gas treatment system of an internal combustion engine (all claimed). #CMT#ADVANTAGE : #/CMT# The compact device ensures efficient and economic treatment of gas without the emission of harmful chemicals into the atmosphere thus enhancing the performance of the internal combustion engine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows a schematic view of an internal structure of a particulate filter. 1 : Particulate filter 2 : Channels 3 : Obstruction 4 : Arrows 5 : Separating walls. #CMT#INORGANIC CHEMISTRY : #/CMT# Preferred Components: The zeolite comprises silicon and aluminum having an atomic ratio of 8:30.
