For a correct interpretation of the

For a correct interpretation of the equilibrium and kinetic data, some basic aspects of the adsorbent have to be previously known; i.e., microporosity, macroporosity, structure of the micropore agglomerations, etc. To determine the macropores existing in the sample, a mercury intrusion analysis was performed. The result, shown graphically in Fig. 3, indicates that the average macroporosity size is 0.3 mm. This value is typical for carbon molecular sieves, although when compared with other CMS samples it looks relatively narrow [2,38].
