✦ Synopsis

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 K [ I] and the anomalous behaviour of samples prepared from almond shells in respect to the adsorption of CO, is discussed. The analysis of the isotherms in terms of percentages of pores filled at different relative pressures gives a good picture of the evolution of the microporosity in the two series of carbons.
