Making zeolite membranes able to separate gas molecules has been a goal of many authors in the last two decades. Zeolite membranes usually have a polycrystalline structure. Permeating molecules can pass through both zeolite pores (intracrystalline pathways) and gaps between crystals (membrane defects or intercrystalline pathways)[1]. The last decade has seen a major breakthrough in the synthesis of high quality zeolite membranes with potential for industrial gas separation and pervaporation applications [2-7]. The separation properties of the membrane are determined by the presence of defects and their adsorption characteristics. Therefore, gas mixture separation through the membrane can be used as a method for.
