<P>PROBLEM TO BE SOLVED: To provide a method for producing a porous support-zeolite membrane composite which can satisfy both practically sufficient processing amount and separation performance in separation and concentration by means of an inorganic material separation membrane. <P>SOLUTION: The method for producing the porous support-zeolite membrane composite comprises: obtaining a zeolite membrane composite by forming a zeolite membrane including zeolite having an SiO<SB POS="POST">2</SB>/Al<SB POS="POST">2</SB>O<SB POS="POST">3</SB>molar ratio of 5 or more on a porous support according to hydrothermal synthesis; subjecting the zeolite membrane composite to heating treatment at temperature of 50°C or more; and immersing the heating-treated zeolite membrane composite in hot water between 40°C and 300°C for 1 hour or more. <P>COPYRIGHT: (C)2013,JPO&INPIT |
