Title:
EXHAUST GAS PURIFICATION FILTER
Document Type and Number:
WIPO Patent Application WO/2020/217774
Kind Code:
A1
Abstract:
Provided is an exhaust gas purification filter comprising a substrate portion, a catalytic layer (17), and a seal portion. The substrate portion has a porous partition (12). The catalytic layer (17) is supported in a pore wall (124) of the partition (12). The partition (12) supporting the catalytic layer (17) contains 10% or less of pores (121) with a pore size of 50 μm or greater. In the pore size distribution for the partition (12) supporting the catalytic layer (17), pore size D50, which is 50% of the accumulative pore volume, is 10 μm or greater. The relationship between pore size D10, which is 10% of the accumulative pore volume, and the pore size D50 satisfies formula I. Formula I: (D50-D10)/D50≤0.9
