Title:

ZEOLITE SEPARATION MEMBRANE AND PRODUCTION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2017/142056

Kind Code:

A1

Abstract:

Provided are: an all-silica zeolite separation membrane for separating carbon dioxide, etc., and not causing a decrease in the processing amount due to water molecule adsorption; and a production method therefor. One aspect of the present invention is a zeolite separation membrane of which the framework is all silica and which has a zeolite crystal structure formed on a porous supporting body, wherein the zeolite crystal structure formed on the porous supporting body is characterized by being fluoride free. Another aspect of the present invention is a production method for a zeolite separation membrane having a zeolite crystal structure on a porous supporting body, the method comprising: a step for producing a seed crystal; a step for applying the seed crystal onto a porous supporting body; a step for producing a membrane synthesis raw material composition; and a step for immersing the porous supporting body having the seed crystal applied thereon in the membrane synthesis raw material composition for causing hydrothermal synthesis to occur, wherein the membrane synthesis raw material composition is characterized by containing a silica source and an organic template, and not containing a fluoride compound.
