Abstract :
Polycrystalline MFI zeolite membranes were prepared on ?-alumina tubular support by hydrothermal treatments at 413 K. The synthesized zeolite membranes were characterized
by XRD, SEM and single gas permeation. The influence of hydrothermal treatment steps and
the calcination time on the zeolite layer formation were investigated. MFI zeolite membrane prepared
by four subsequent hydrothermal treatments and calcined at 673K for 30 h had optimum quality from morphological and crystalline point of view. The grown MFI zeolite layer was uniform with about 20 µm thickness and well-intergrown zeolite crystals.
