Abstract

Reactivities in 0.1 MPa of air of seven chars obtained as residues in selected coal conversion processes have been determined at temperatures below their processing conditions. Even though reactivities vary by some 200 times, activation energies for reaction, as determined from Arrhenius plots, are all close to 130 kJ/mole. Differences in reactivities are related to differences in parent coal rank and residence times and temperatures used upon the conversion of the coals to chars.
