CERAMIC SEPARATION MEMBRANE STRUCTURE, AND REPAIR METHOD THEREOF

摘要

There are disclosed 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 33 is disposed on a ceramic porous body 9, and defects of the zeolite separation membrane 33 are repaired by zeolite repaired portions 34 containing zeolite of structure different from the structure of zeolite of the zeolite separation membrane 33. The zeolite separation membrane 33 and the zeolite repaired portions 34 are made of a hydrophobic zeolite having a ratio of SiO 2 /Al 2 O 3 = 100 or more.
