✦ Synopsis

It is shown that the values of the structural constant B and of the micropore volume W, 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 ultramicrop?rosity, present in heterogeneous carbons, and to activated diffusion into typical micropores, through constrictions. It is suggested that the quantity B is not necessarily a constant for a given solid, as assumed previously.
