Illinois 6 coal (hvBb) was weathered for up to 330 days at 25 and 80/degree/C with humid air. Its behavior was compared with Pittsburgh Seam (hvAb) and Horsepen Seam (mvb) coals weathered under the same conditions. The weathering rate showed a strong dependence on temperature and coal rank. At 25/degree/C, the Illinois 6 coal showed much more substantial changes in chemical and physical properties upon weathering. Spectroscopic data indicate that the concentration of organic oxygen groups in the coal may eventually level off. Two potential causes of this behavior are proposed. Thermal (non-oxidative) treatment at 80/degree/C has little effect on the chemical and physical properties of a fresh hvAb coal.
