“…Kita [191,197,199] performed plasma polymerization of tetraethoxysilane (TEOS) and perfluoro-n-hexane (PFH) in order to control the size of the zeolitic membrane pores. Furthermore, he analyzed gas permeation at 35±200 C using single-component H 2 , He, CO 2 , N 2 , CH 4 , and SF 6 .…”

“…Fluxes and separation properties decrease with time probably due to pore obstruction caused by feed impurity or by species produced in catalytic reactions. Kita [191,197,199] prepared three different membranes formed by zeolite layers (A, ZSM-5 and Y) on cylindrical alumina supports, and he analyzed them with respect to pervaporation and vapor permeation. The zeolitic membrane with NaA films was found to be highly selective for water, and is characterized by high fluxes.…”

Zeolite membranes are the focus of much active research due to their extensive potential applications, particularly their superior catalytic and separation properties. Synthesis methods and properties are presented here and compared with those of the zeolite crystalline powders. This review concentrates on composite membranes, the Figure showing the surface of an alumina composite membrane with MOR structure.
