▎ 摘　　要

NOVELTY - A zeolite separation membrane is obtained by bonding zeolite microcrystal materials (10) mutually. The surface of zeolite microcrystal material is coated using graphene oxide and the zeolite microcrystal material is bonded without gap through the graphene oxide. USE - Zeolite membrane is used for separating mixed gas. ADVANTAGE - The zeolite separation membrane has excellent separation property with respect to pores of zeolite crystal, and is manufactured with excellent reliability, by simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of zeolite separation membrane, which involves preparing a dispersion liquid by dispersing the zeolite microcrystal material and the graphene oxide in water, adhering the graphene oxide in the surface of zeolite microcrystal material in the dispersion liquid, filtering the zeolite microcrystal material covered with the graphene oxide from the dispersion liquid, and obtaining zeolite separation membrane. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the structure of zeolite separation membrane. Zeolite microcrystal material (10) Graphene (12) Support material (14)
