## It is proposed that adsorption isotherms of water vapor determined on non-porous carbons can be classified into four distinct types, and that a certain level of polarity and distribution of polar sites is associated with each. Examples of each water isotherm type have been obtained by modificat

Nitrogen isotherms have been determined at 77 K on four active carbons, used as adsorbents in gas masks, before and after n-nonane ~readsorption. The four carbons contain both micro and mesopores. After n-nonane preadsorption, mesoporosity is still observed, together with a, low pressure hysteresis
Chars, prepared by pyrolysis of prune pits at I or lS"C/min to 500, 700 or 9OO"C, were subsequently gasified by CO, at 900Β°C. Pyrolysis conditions did not significantly affect the porosity developed for a given mass loss due specifically to gasification reactions, i.e. excluding additional pyrolytic
Carbons were prepared from carbonized polyvinylidene chloride (850Β°C) by activation with CO, at 830Β°C to 85 per cent burn-off. Characterization of these carbons was made from gas phase adsorption data using nitrogen (77Β°K) and carbon dioxide (195" and 273Β°K) as adsorbates in conjunction with the Dub
