| dc.description.abstract | on-exchange processes on zeolites hold promise for improving adsorption mechanisms critical for post-combustion CO2 capture (PCC). Zeolites offer advantages such as favourable CO2 adsorption isotherms, rapid kinetics, non-toxicity, and cost-effectiveness, making them attractive candidates for carbon capture applications. In this study, we focus on exploring the impact of ion-exchange (K+ and Ca2+) on bare NaY zeolite for PCC. Fixed-bed breakthrough experiments were conducted on various ion-exchanged zeolites, including K(23)Y, K(58)Y, K(95)Y, Ca(56)Y, and Ca(71)Y, within a temperature range of 306 K to 344 K and pressures reaching up to 350 kPa. The objective of these experiments is to investigate the equilibrium, kinetics, and dynamic characteristics of the sorption process, covering both single and binary mixtures of CO2 and N2. Performance parameters such as selectivity and working capacity were evaluated based on the experimental outcomes. Following data collection, a mathematical model was calibrated utilizing Aspen Adsorption v10 software to simulate fixed-bed performance under standard PCC conditions. | pt_PT |
