## 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

## Reactivities of seventeen 40 x 100 mesh (U.S.) coals charred to 1000ยฐC have been measured at 910ยฐC in 0.1 MPa of a N2-Hz0 mixture containing water vapour at a partial pressure of 2.27 kPa. Char reactivity decreases, in general, with increasing rank of the parent coal. The chars show a 250-fold

Reactivities of sixteen 40 x 100 (U.S.) mesh U.S. coals charred to 1000ยฐC were measured in carbon dioxide at 900ยฐC. Chars derived from coals with less than 80% carbon, on a dry-ash-free basis, were the most reactive. These chars also gave the widest spread in reactivity. Plots of inorganic element
