| Summary: | Nitrogen and carbon dioxide adsorption methods were used to study the structural properties developed by a series of alumina-pillared clays. The solids were prepared by varying the Al/clay ratio and the calcination temperature of a montmorillonite intercalated with solutions of aluminium. Equilibrium data for CO 2 adsorption by these materials were analyzed using the Langmuir, Freundlich and Toth isotherm models. The fitting parameters for these models demonstrated the heterogeneous nature of the materials studied and that CO 2 interaction with the surface was influenced by the calcination temperature. |
