ABSTRACT
Zeolites are nanometer-sized crystalline porous materials. Their small pore size and the possibility of having different chemical compositions can give rise to a very selective interaction with adsorbed molecules depending on size, shape, and chemical compositions. A zeolite’s surface can be changed from hydrophobic to hydrophilic and nonacidic to acidic simply by substitution of Si by Al, which signižcantly affects structural property-related phenomena such as diffusion. During the last 10 years, interest in developing thin zeolite žlms or zeolite membranes has grown enormously [1,2]. Zeolite membranes are generally used as a catalytic membrane reactor, as it can combine separation [3-7] and catalytic activity [8] efžciently due to the signižcantly different diffusivities in the uniform, molecular-sized pores and the
