摘要：
The adsorption of nitrogen on hydroxylated γ-alumina that had been subjected to various thermal treatments in order to dehydrate it was studied by means of experimental adsorption isotherms at different temperatures. The experimental adsorption energy, determined macroscopically from the heat curve or from the BET model, was interpreted at the molecular level by calculating the adsorption potential using for the distribution of the solid's force center a model based on Peri's classical bidimensional model for the surface of alumina. © 1992.
