N2 - In this study, the influence of hydrothermal temperature and time at zeolite X supported on glasswool were investigated. The results of characterization using XRD showed that a single phase zeolite X with highest crystallinity was obtained when hydrothermal temperature and time at 100°C during 24 hours (ZXF100-24H). The CO2 adsorption capacity of ZXF100-24H has reached up to 10.15 wt. %. Kinetics of CO2 adsorption onto zeolite X supported on glasswool was investigated using pseudo-first-order, pseudo-second-order and intra-particle diffusion kinetic models. After evaluating three kinetic models for CO2 adsorption at adsorption temperatures of 30°C, 40°C and 50°C, it was found that intra-particle diffusion kinetic model provided the best fitting for the adsorption data. Furthermore, the thermodynamic parameters of CO2 adsorption were obtained as follows, Gibbs free energy change (ΔG°) are-0.409 kJ/mol at 30°C,-0.274 kJ/mol at 40°C and-0.138 kJ/mol at 50 °C, whereas the enthalpy change (ΔH°) is-4.53 kJ/mol and the entropy change (ΔS°) is-0.0135 kJ/(mol K).
