dc.description.abstractIon-exchange was performed on bare commercial binder-free NaY zeolite with alkali (K+) and alkaline earth (Ca2+) metal cations in the range 23, 58, and 95% exchange for K+, and 56 and 71% for Ca2+, to be used as candidates regarding CO2 post-combustion capture (PCC) and biogas upgrading by adsorption processes. Adsorption equilibrium isotherms of CO2, CH4 and N2 were measured on all these cation-exchanged samples using a chromatographic technique between 308 and 348 K and pressures up to 350 kPa and modelled by the dual-site Langmuir isotherm. The CO2 adsorption capacity increases as Na+ is exchanged further by K+ and the reverse for the Ca2+ exchange. The single- and binary-component breakthrough curves were numerically simulated and accurately predicted using the Aspen Adsorption package. This work discloses the importance of ion-exchange on binder-free beads of NaY zeolite to improve its performance in PCC and biogas upgrading applicationspt_PT
