HIGH SILICA CDS-1 ZEOLITE - NAT INST OF ADVANCED IND SCIEN

Title:

HIGH SILICA CDS-1 ZEOLITE

Document Type and Number:

WIPO Patent Application WO/2005/047182

Kind Code:

A1

Abstract:

Disclosed are a high silica zeolite having a novel crystal structure, a zeolite membrane and methods for producing them. The zeolite is represented by the chemical composition:[(Si_36-xT_y·O₇₂)·M_z] (wherein M represents a cation of an alkali metal such as Li, Na, K and Rb; T represents Al, Ga, Fe and Ce as skeleton substituting elements; and x satisfies 0 ≤ x ≤ 3.0, y satisfies 0 ≤ y ≤ 1.0, and z satisfies 0 ≤ z ≤ 3.0), and has a micropore composed of a covalent bond of Si-O. The zeolite has a specific diffraction peak at 2Ѳ in the powder x-ray diffraction pattern.
