## Reactivities of eighteen 40 x 100 mesh U.S. coals charred to 1000ยฐC have been measured in H2 at 2.7 MPa and 980ยฐC. 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
