Title:
POROUS SUPPORT-ZEOLITE MEMBRANE COMPOSITE
Document Type and Number:
WIPO Patent Application WO/2013/125661
Kind Code:
A1
Abstract:
A porous support-zeolite membrane composite obtained by forming a zeolite membrane on an inorganic porous support, wherein the zeolite membrane contains a zeolite having a microporous structure composed of rings which each contain at most 8 oxygen atoms. In the porous support-zeolite membrane composite, the SiO2/Al2O3 molar ratio at the surface of the zeolite membrane is larger than that of the zeolite membrane itself by 20 or more, or the water adsorption of the porous support-zeolite membrane composite as determined from the water vapor adsorption isotherm at a relative pressure of 0.8 is at least 82% of the water adsorption of the composite as determined under the same conditions as described above after one-week immersion of the composite in a 90 mass% aqueous acetic acid solution at room temperature.
