Title:
METHOD FOR PRODUCING ZEOLITE MEMBRANE STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2018/180211
Kind Code:
A1
Abstract:
Provided is a method for producing a zeolite membrane structure (10), the method comprising: an immersion step for immersing a porous substrate (20) in a synthetic sol; and a synthesis step for hydrothermally synthesizing a zeolite membrane (30) on the surface of the porous substrate (20) that has been immersed in the synthesis sol. When the foamability of the synthetic sol is determined by the Ross-Miles method under a condition of 25°C, the foam height 5 minutes after downward flow ends is 5 mm or less.
