Gas adsorption on zeolites gains remarkable attention in this new area of technology since it has industrial importance in many process industries. New technologies involving catalysis, gas separation, gas purification, gas storage, and high temperature gas sensor hold a great promise for industrial applications. In order to develop and design an efficient and economically feasible process, it is important to understand the adsorption characteristics of gas on zeolites. In this study, different zeolites adsorbents were synthesized and modified for gas separation by adsorption. For improvement of their properties as gas adsorbent, some methods like nano material synthesis were used. In this study because of damaging effect of removing structure directing agents from zeolite framework like reduction in crystallinity and make crystal defect and also the organic molecules, that contribute up to 25% of the overall zeolite synthesis cost, are completely degraded after calcinations, zeolite either as powder or layer synthesized without using these materials. For adsorbent synthesis at fist fine powders of different zeolites were synthesized. In the case of X, LTL and LTA zeolite powders, the particle size was less than 100 nanometers and for Y and ZSM-5 was less than 2 microns. The powders were used in both layers synthesizing and shaping. In layers synthesis powders were used as seed which after holding in synthesis condition in synthesis solution with different method, they grown and form a layer on the support. Powders and layers characterized with X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) to identifying better conditions and composition for each zeolite powder and layer. In the case of shaping zeolite powders were shaped by means of polyelectrolyte. In this study we used Sodium Alginate as polyelectrolyte. After calcinations zeolite adsorbent was prepared from zeolite fine powders. SEM image show that zeolite particles was sintered and because of large pore that exist in its structure it has suitable porosity and specific surface area. For modifying adsorbent, they were ion exchanged with Lithium, Sodium, Potassium, magnesium and zinc cations. Keywords: Zeolite, Nano particle, Adsorbent, Synthesis, Layer synthesis, Shaping.
