Document Type and Number:
WIPO Patent Application WO/2016/208728
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a zeolite that can sufficiently increase catalyst density and that also sufficiently increases the contact efficiency between exhaust gas and a catalyst and can thereby remarkably improve NOx-purification performance. This zeolite has a CHA structure, has an average particle diameter, as measured by SEM image, of 0.05 μm or more but less than 1.0 μm, and has an average aspect ratio of 1.1-3.0.
