Title:
OLEFIN SEPARATION METHOD AND ZEOLITE MEMBRANE COMPLEX
Document Type and Number:
WIPO Patent Application WO/2015/141686
Kind Code:
A1
Abstract:
The present invention provides an olefin separation method that employs a zeolite membrane complex having high separation capability, and endowed with a permeation rate sufficient for practical purposes; and a zeolite membrane complex for olefin separation. The present invention is a method for selective separation of an olefin from an olefin/paraffin mixed fluid, using a zeolite membrane complex having a zeolite X film formed on a porous substrate, characterized in that the zeolite X is composed of an AgX zeolite in which the ion-exchangeable cations within the zeolite X have undergone ion exchange with Ag ions.
