Burning profiles in air obtained on a thermogravimetric analyzer (TGA) were used to study combustion behavior of residues produced in thermal and catalytic coal hydrogenation experiments. The characteristic combustion temperatures, T_<0.01>, T_<0.1>, T_<0.5>, T_<0.9> and T_p, were determined in the burning profiles and were used to represent the reactivity of these residues. Lower characteristic temperatures were found for the samples with higher H/C ratio and VM content. In particular, the effects of remained hydrogenation catalysts and enriched coal mineral matters on reactivity of residues were validated and discussed.
