HONEYCOMB-SHAPED GAS SEPARATION MEMBRANE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a honeycomb-shaped gas separation membrane structure dispensing with a support for supporting a gas separation membrane, increased in its membrane area, simple in its production process and capable of being reduced in cost. SOLUTION: A gas separation membrane structure 1 for separating or supplying specific gas from mixed gas has a monolithic honeycomb structure and comprises a dense body comprising oxide of a brownmillerite structure.
