The hydrogen transfer behaviors of the Illinois No.6 coal on its thermal and catalytic (with Pt/Al_2O_3) reactions with the gas-phase H_2 have been investigated using a tritium tracer method. The reactions were carried out in a fixed bed reactor in the temperature ranging from 250 to 400℃ under the tritiated hydrogen gas pressure of 5.0MPa for 1h. The experiments in the presence of the Pt/Al_2O_3 gave some insights into the changes in oxygen functional groups induced by hydrogen transfer, and the promotion of benzylic radical formation and the degradation reactions of the coal matrix.
