The magnetic susceptibility and magnetic resonance spectroscopy of coals doped with Ni have been measured as a function of heat treatment temperature (HTT). Both the susceptibilities and magnetic resonance signals began increasing at H'lT of 300 to 500ยฐC by a factor of lo\\* to 103. The HTT correspo

Samples of a vitrinite concentrate of Balmer 10, medium-volatile bituminous coal (433) and high-volatile Moss 3 coal (535) were oxidized in air at 85ยฐC for four days to partially destroy the swelling characteristics as measured by the Ruhr dilatometer. Similar samples were oxidized at 100ยฐC for thre
