Title: ZEOLITE MEMBRANE COMPLEX
Abstract:
A zeolite membrane complex for transmitting and separating highly permeable components from a gas mixture or liquid mixture comprising a plurality of components, the zeolite membrane including CHA-type aluminosilicate zeolite, and, in an X-ray diffraction pattern obtained by irradiating a membrane surface with X rays, the peak intensity near 2θ = 17.9° having a value less than 0.5 times the peak intensity near 2θ = 20.8°, and the peak intensity near 2 θ = 9.6° having a value 2.0 to less than 4.0 times the peak intensity near 2θ = 20.8°, and the zeolite membrane being formed on an inorganic porous support.
