The evolution of the porosity in two series of samples prepared by the reaction of two activated carbons (from almond shells and olive stones) with air at 350°C has been followed by adsorption of CO2 (273 and 298 K) and n-butane (273 K). The results have been compared with the adsorption of N, at 77

Activated carbons have been prepared from a semianthracite preoxidised in air to different degrees. The activation has been carried out in steam at 850°C to 5Ok 1% burnoff. The adsorption isotherms of nitrogen at 77 K and COZ at 273 K have been determined. The adsorption isotherms indicate that the
