Abstract

MORDENITE is a high silica zeolite which is synthesized from a gel with different oxide molar ratios at various temperatures. The zeolite is widely used as adsorbents in the separation of gas or liquid mixtures and also as catalysts for naphtha and xylene isomerization in petroleum industries and petrochemical complexes. MORDENITE crystallites with the size of 77-93 nm were hydrothermally synthesized from a gel with the different oxide molar ratios (Na2O/Al2O3 = 1-2.5 and SiO2/Al2O3 = 10, 16) aged at 30oC for 0 to 3 days in a Teflon lined autoclave at crystallization temperatures of 155 and 175oC. Different techniques like XRD, FT-IR, SEM, BET, and EDX were used to characterize the as-synthesized zeolite samples and to analyze their physicochemical properties as well. Results obtained from the present work illustrated that the nano-sized MORDENITE zeolites with rod (high aspect ratio) and ellipsoidal morphologies were synthesizable with the gel compositions mentioned above. Preparation of such uniform morphologies for MORDENITE from the gel compositions used in this work in the absence of an organic template has not been yet reported.
