Abstract: The aim of this research is to enhance CO2 adsorption capacity of zeolite NaA by modifying its surface properties. In this work, zeolite NaA was synthesized by using sodium metasilicate and anhydrous sodium aluminate as silicon and aluminium sources, respectively. The synthesized zeolites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and N2 adsorption-desorption techniques. The effect of aging time on surface properties and CO2 uptake were studied. Increasing of aging time led to lowering of CO2 adsorption capacities which was due to agglomeration and resulted in lowering of zeolite crystallinities. Tetramethylammonium hydroxide (TMAOH) was used to control the crystalline size of zeolite. The results showed that zeolite size slightly decreased by increasing of TMAOH content. TMAOH facilitated the formation of anionic silicate and increase the degree of supersaturation of Si species which resulted in decreases of particle sizes.
