The proton magnetic resonance thermal analysis (PMRTA) method has been applied to the reaction of a bituminous coal with elemental sulfur (S8). From the non-isothermal PMRTA data including mobile and rigid hydrogen fractions, it is revealed that the dehydrogenation reactions are accelerated by S8 at temperature above 250°C The dehydrogenation reactions accompanied a decrease in mobile hydrogen and fusibility, resulting in an increase in the proportion of hydrogen that is rigid.
