This study investigates the efficiency of zeolite 13X in capturing CO₂ and toluene, a representative volatile organic compound (VOC), under realistic environmental conditions. Zeolite 13X is widely recognized for its high surface area and selective adsorption properties, making it a promising candidate for air purification and carbon capture applications. The study assesses the material’s adsorption capacity and reusability in conditions that mimic practical applications, including varying temperatures, humidity levels, and gas concentrations. Results indicate that zeolite 13X exhibits a high adsorption capacity for both CO₂ and toluene under dry conditions; however, this capacity becomes negligible under wet conditions due to the material’s strong hydrophilicity, which leads to preferential adsorption of water molecules. Regeneration tests further demonstrate the material’s durability and potential for repeated use, with minimal loss in adsorption capacity after multiple cycles. These findings underscore the importance of evaluating gas capture performance under realistic conditions to accurately assess the material’s practical viability and optimize its application in air purification and carbon capture technologies.
