Abstract

Official abstract text for this publication.

A peak intensity of a (002) plane is greater than or equal to 0.5 times a peak intensity of a (100) plane in an X-ray diffraction pattern obtained by irradiation of X-rays to a membrane surface of the ERI membrane.

First claim

Opening claim text (preview).

The invention claimed is: 1. A zeolite membrane having an ERI structure, wherein a peak intensity of a (002) plane is greater than or equal to 0.5 times a peak intensity of a (100) plane in an X-ray diffraction pattern obtained by irradiation of X-rays to a membrane surface of the zeolite membrane. 2. The zeolite membrane having an ERI structure according to claim 1 , wherein the peak intensity of the (002) plane is greater than or equal to 0.9 times the peak intensity of the (100) plane. 3. The zeolite membrane having an ERI structure according to claim 1 or 2 , the zeolite membrane comprising two or more of Si, Al and P. 4. The zeolite membrane having an ERI structure according to claim 3 , the zeolite membrane comprising at least Al, P and O. 5. A membrane structure comprising the zeolite membrane having an ERI structure according to claim 1 , and a porous support configured to support the zeolite membrane having an ERI structure.
