High quality faujasite membranes were prepared using hydrothermal treatments. Tubular Porous Mullite
Supports were fabricated from Kaolin clay by a temperature-programmed calcination treatment, following a
leaching treatment. As observed in SEM photographs, the porosity of the support increased during the
leaching treatment. The NaX faujasite zeolite powders were prepared hydrothermally and characterized with
XRD and SEM. The best crystalline powder and the corresponding starting gel were respectively used for
seeding treatment and hydrothermal crystallization of a thin, continuous and fully covering X-type zeolitic
top layer on outer surface of the cylindrical support. The membrane was characterized with XRD and SEM.
