Résumé
It is shown that the values of the structural constant <i>B</i> and of the micropore volume <i>W<sub>o</sub></i> can change considerably for certain active carbons, when the adsorption of simple gases is measured over a large range of temperature. The changes are probably related to ultramicroporosity, present in heterogeneous carbons, and to activated diffusion into typical micropores, through constrictions. It is suggested that the quantity <i>B</i> is not necessarily a constant for a given solid, as assumed previously.
