POROUS SUBSTRATE WITH SEED CRYSTAL-CONTAINING LAYER FOR MANUFACTURING ZEOLITE MEMBRANE, ZEOLITE MEMBRANE AND METHOD FOR MANUFACTURING ZEOLITE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a porous substrate with a seed crystal-containing layer used for manufacturing a zeolite membrane which is capable of inhibiting a defect such as a crack from being generated in the zeolite layer upon manufacture or use by manufacturing a zeolite membrane by the use of the substrate and capable of being subjected to air-spraying, washing and processing for the purpose of removing a foreign substance, etc., prior to hydrothermal synthesis.;SOLUTION: The porous substrate with the seed crystal-containing layer for manufacturing a zeolite membrane is obtained by loading a seed crystal-containing layer containing zeolite powder and ceramic powder to function as a seed crystal for forming a zeolite membrane on the surface of a ceramic porous substrate and fired to fix the seed crystal-containing layer on the porous substrate.;COPYRIGHT: (C)2008,JPO&INPIT
