Applying the theories for resistivity of the amorphous and granular materials, the temperature dependence of the electrical resistivity of coals, heat treated at different temperatures, has been successfully explained in terms of structural parameters obtained by X-ray measurements.
## Reactivities of eighteen 40 x 100 mesh U.S. coals charred to 1000Β°C have been measured in H2 at 2.7 MPa and 980Β°C. The char-hydrogen reaction usually occurs in two stages: a slow induction period followed by a constant-rate region. Reactivities of various chars in the initial stage (Ri) decreas
