Changes induced by Z&l,-impregnation in the development of spin population profiles during the in situ pyrolysis of a bituminous coal were investigated as a function of cell geometry, carrier gas flow rate and heating rate. At a heating rate of 10Β°C min -' , ZnCl, was observed to lower spin populati
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
