Title:
FILTER FOR EXHAUST GAS CLEANING AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2018/159214
Kind Code:
A1
Abstract:
The present invention provides a filter for exhaust gas cleaning that can efficiently burn and eliminate microparticle components collected in partitions and a method for manufacturing the same. This filter (CSF) for exhaust gas cleaning is characterized: by at least including a honeycomb base material having porous partitions for collecting soot and other microparticle components (PM) in exhaust gas, and a catalyst, which is a catalyst supported on the honeycomb base material, for burning and eliminating the microparticle components collected in the partitions in the honeycomb base material and deposited in a cell; and in that the catalyst is carried intensively in shallow parts from the cell wall surfaces on the exhaust gas inlet side of the honeycomb base material with 65% or more of the total mass of the catalyst being present in a depth region from the cell wall surface in the honeycomb base material to 2/10a based on wall thickness a for the partitions.
