METHOD OF FABRICATING ORGANIC STRUCTURE DIRECTING AGENT-FREE CHA TYPE ZEOLITE MEMBRANE AND MEMBRANE FABRICATED THEREBY

摘要

The present invention relates to a method of fabricating an organic structure directing agent-free CHA type zeolite membrane and a membrane fabricated thereby, and more particularly to a method of fabricating a continuous CHA type zeolite membrane, which exhibits CO₂/N₂ and CO₂/CH₄ separation performances comparable with those of conventional membranes, in a cost-effective manner without a calcination process by hydrothermal synthesis using an alkali metal hydroxide without using an organic structure directing agent, and to a membrane fabricated thereby.
