“…Such enhancement has also been reported for CO 2 capture, in which Walton et al studied the performance of alkali metal cation-exchanged NaX and NaY in CO 2 adsorption, and the results revealed that Li + cation could enhance CO 2 uptake in both zeolites. Another study indicated that in alkali metal cation-exchanged zeolite X, with the increase in the cationic radius, the CO 2 /N 2 selectivity increased. − …”

The adsorption equilibria and kinetic performance of CO 2 , CH 4 , and N 2 on pelletized cation-exchanged faujasite zeolites (with alkali, alkaline earth, and transition metal ions) have been investigated by an innovative volumetric apparatus simultaneously. The standard instrumental analytical techniques, including X-ray diffraction, field emission scanning electron microscopy, energy dispersive X-ray spectroscopy (EDX), and atomic absorption spectroscopy (AAS), were utilized to characterize binder-free modified zeolites. EDX and AAS analyses revealed that the ion exchange was successfully achieved. The results indicate that the type of cation present in the zeolite framework and the Si/Al ratio can have a significant impact on the adsorption capacity and kinetic performance. The obtained isotherms were determined by three isotherm models, and the Langmuir−Freundlich (Sips) model was found to show the best agreement with the experimental isotherm data for all gases. The CO 2 uptakes of KX, MgX, and CaX reached 4.13, 4.79, and 5.48 mmol/g, respectively. The effective binary and kinetic selectivities of CO 2 /CH 4 and CO 2 /N 2 were also calculated. Among all samples, KX showed the highest CO 2 /CH 4 and CO 2 /N 2 selectivities of 54.46 and 91.62, respectively. Pseudo-first-, pseudo-second-order, and Avrami kinetic models were fitted to the experimental kinetic data to analyze the adsorption kinetics. Finally, the macropore diffusion coefficient (D p ) and microporous diffusional time constant (D c /r c 2 ) were estimated by correlating the micropore−macropore kinetic model with the experimental fractional uptake curves. Among the ion-exchanged zeolite samples, the K + form exhibits a suitable performance in terms of kinetic behavior and adsorption capacity.
