Abstract:
A process for producing a zeolite membrane composite includes a step of obtaining FAU-type seed crystals, a step of depositing the FAU-type seed crystals on a support, a step of forming an AFX-type zeolite membrane on the support by immersing the support in a raw material solution and growing an AFX-type zeolite from the FAU-type seed crystals by hydrothermal synthesis, and a step of removing a structure-directing agent from the AFX-type zeolite membrane. In this way, the AFX-type zeolite membrane can be provided.
