Abstract: Understanding the adsorption mechanism is essential for developing efficient technologies to capture carbon dioxide from industrial flue gases. In this work, laboratory measurements, density functional theory calculations, and molecular dynamics simulations were employed to study CO2 adsorption and diffusion behavior in LTA-type zeolites. The CO2 adsorption isotherms measured in zeolite 5A are best described by the Toth model. Thermodynamic analysis indicates that the adsorption process is spont[...]
Our summary: Study of CO2 adsorption and diffusion in LTA-type zeolites using laboratory measurements, DFT calculations, and molecular dynamics simulations. Thermodynamic analysis shows spontaneous and exothermic adsorption with heterogeneous interactions at Ca2+ and Na+ sites. Comparison between zeolites 5A and ITQ-29 reveals differences in adsorption energy and diffusion kinetics.
