Activated carbons have been prepared from a semianthracite preoxidised in air to different degrees. The activation has been carried out in steam at 850Β°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
