Ceramic separation membrane structure, and repair method thereof
A ceramic separation membrane structure in which a zeolite separation membrane formed on a ceramic porous body is repaired, and a repair method thereof. In the ceramic separation membrane structure, a zeolite separation membrane is disposed on a ceramic porous body, and defects of the zeolite separation membrane are repaired by zeolite repaired portions containing zeolite of structure different from the structure of zeolite of the zeolite separation membrane. The zeolite separation membrane and the zeolite repaired portions are made of a hydrophobic zeolite having a ratio of SiO2/Al2O3=100 or more.
