In this Study, a new synthesized Y-type zeolite (NaY) was modified with diethanolamine and 3-aminopropyltrimetoxysilane, in order to probe the influence of the modification of the adsorbent’s surface on CO2 desorption. The surface nature of NaY was changed after modification, which causes a significant increase in the CO2 adsorption capacity. The CO2 adsorption capacity of the modified NaY increased with temperature. The adsorbents were characterized by TPD-CO2 Technique. These results showed that functionalized NaY zeolites have excellent potential for CO2 adsorption at high temperatures.
