SOLVENT-RESISTANT SEALING STRUCTURE OF ZEOLITE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a novel solvent-resistant sealing technique of a zeolite membrane used in a state immersed in an organic solvent in an organic chemical reaction process or the like.

SOLUTION: In the solvent-resistant sealing structure of the zeolite membrane has a support for supporting the zeolite membrane, a cap for sealing the support mechanically and comprising a dense material having a predetermined wall thickness and the swellable resin filling the gap between the support and the cap and swollen under a reaction atmosphere. In the solvent-resistant sealing method of the zeolite membrane, the support (A) of the zeolite membrane is mechanically sealed by the cap (B) comprising a dense material which has the minimum inner radius 1.01-1.50 times the maximum outer diameter of the support (A) and a wall thickness 0.05 times the minimum inner diameter and the gap between (A) and (B) is embedded with the swellable resin (C) swollen in a reaction atmosphere. A zeolite membrane-containing sealing structure is also disclosed.
