Abstract
Charcoal prepared by heating walnut shells at 500 °C in a nitrogen atmosphere was activated by CO2 at various temperatures. The adsorption equilibrium and mass transfer characteristics of the activated carbon were studied. The structural properties were determined by means of additional measurements. A pore model is proposed to explain the variation of the pore structure with the activation process. The micropore sizes predicted by the model agree with the adsorption data.
