It is shown that the oxidation of an Asturian bituminous coal by air, at 150" and 27O"C, has a considerable influence on the microporous structure of the carbon obtained by subsequent carbonization and steam activation to 50% burn-off. The direct activation of the coal leads to an open micropore sy
