METHOD FOR PRODUCING SEPARATION MEMBRANE USING MFI-TYPE ZEOLITE (SILICALITE)
Provided is a method for producing a separation membrane including a silicalite membrane without using NaOH or the like that causes an increase in cost with respect to equipment, facilities, and process time. The method for producing a separation membrane is a method for producing a separation membrane including a porous support and a silicalite membrane that is formed on the support and has an MFI-type zeolite crystal structure, and is characterized in that the method includes a step of producing a seed crystal, a step of attaching the seed crystal onto the porous support, a step of producing a membrane synthesis raw material composition containing SiO 2 , an organic template, and H 2 O, and a step of immersing the porous support having the seed crystal attached thereto in the membrane synthesis raw material composition and performing hydrothermal synthesis, and the composition ratio of the membrane synthesis raw material composition is as follows: SiO 2 :organic template:H 2 O = 1: (0.05 to 0.15) : (50 to 120).
