CHA-OFF-ERI INTERGROWTH STRUCTURE MOLECULAR SIEVE, PREPARATION METHOD THEREFOR, CATALYST THEREFOR AND USE OF CATALYST

Document Type and Number:

WIPO Patent Application WO/2022/068604

Kind Code:

A1

Abstract:

Provided are a CHA-OFF-ERI intergrowth structure molecular sieve, a preparation method therefor, a catalyst therefor and the use of the catalyst. The CHA-OFF-ERI intergrowth structure molecular sieve is a molecular sieve formed by the intergrowth of an OFF-ERI intergrowth structure molecular sieve and a CHA structure molecular sieve, and has both CHA and OFF-ERI topological structures, with the silica-alumina ratio thereof being in the range of 5-200. The CHA-OFF-ERI intergrowth structure molecular sieve of the present invention has advantages such as hierarchical pore channels, various microporous structures, adjustable acidity and high reactivity.
