SEPARATION MEMBRANE STRUCTURE
To provide a separation membrane structure capable of achieving both of permeability and separation performance.SOLUTION: A separation membrane structure 10 includes: a porous support body 20 composed of ceramics; a first separation membrane 30 formed on the porous support body 20; and a second separation membrane 40 formed on the first separation membrane 30. The second separation membrane contains at least one or more kinds of cations selected from among alkali metal, alkali earth metal, Au, Ag, Cu, Ni, Co, Pd and Pt. The first separation membrane 30 and the second separation membrane 40 are composed of zeolite of the same skeletal structure selected from among BEA, DDR, CHA and MEL. A Si/Al atomic ratio of the second separation membrane 40 is smaller than that of the first separation membrane 30.SELECTED DRAWING: Figure 4
【課題】透過性能と分離性能を両立可能な分離膜構造体を提供する。【解決手段】分離膜構造体１０は、セラミックスによって構成される多孔質支持体２０と、多孔質支持体２０上に形成される第１分離膜３０と、第１分離膜３０上に形成される第２分離膜４０とを備える。第２分離膜は、アルカリ金属、アルカリ土類金属、Ａｕ、Ａｇ、Ｃｕ、Ｎｉ、Ｃｏ、Ｐｄ及びＰｔから選ばれる少なくとも１種類以上の陽イオンを含有する。第１分離膜３０及び第２分離膜４０は、ＢＥＡ、ＤＤＲ、ＣＨＡ及びＭＥＬから選択される同じ骨格構造のゼオライトによって構成される。第２分離膜４０のＳｉ／Ａｌ原子比は、第１分離膜３０のＳｉ／Ａｌ原子比よりも小さい。【選択図】図４
