ZEOLITE MEMBRANE COMPOSITE
PROBLEM TO BE SOLVED: To provide a zeolite membrane composite having excellent characteristics in separation of a gas mixture.SOLUTION: A zeolite membrane composite is used in order to permeate a component having high permeability from a gas mixture composed of a plurality of components to separate the same, and includes a zeolite of a CHA type aluminosilicate, and a zeolite membrane in which molar ratio (monovalent metal/Al molar ratio) of a monovalent metal element to Al in a surface of the zeolite membrane is 0.3 or more, formed on an inorganic porous support.SELECTED DRAWING: None
【課題】気体混合物の分離に優れた特性を持つゼオライト膜複合体を提供する。【解決手段】複数の成分からなる気体混合物から、透過性の高い成分を透過して分離するために用いるゼオライト膜複合体であって、ＣＨＡ型アルミノ珪酸塩のゼオライトを含み、ゼオライト膜表面のＡｌに対する１価金属元素のモル比（１価金属／Ａｌモル比）が０．３以上であるゼオライト膜が、無機多孔質支持体上に形成されてなるゼオライト膜複合体。【選択図】なし
