Repair method of oxygen separation membrane, a method of reproducing oxygen separation membrane, an oxygen separation membrane, membrane type oxygen separation device, and the membrane reactor

摘要

PROBLEM TO BE SOLVED: To provide a repairing method of oxygen separation membrane easily repairing defective parts such as pin holes of the oxygen separation membrane consisting of mixed conductive ceramic having oxygen ion conductivity and electron conductivity.;SOLUTION: Repairing paste containing silver- and copper-containing metal powder, or repairing paste containing cobalt oxide powder and mixed conductive oxide powder is coated on defective parts caused in the oxygen separation membrane, selectively permeating and separating oxygen from oxygen-containing gas, and consisting of mixed conductive ceramic having oxygen ion conductivity and electron conductivity, and the membrane is heat-treated at a temperature fixing the coated repair paste, to form an airtight fixed layer for repairing.;COPYRIGHT: (C)2008,JPO&INPIT
