The uncatalysed hydrogenation of a bituminous coal in a batch reactor with tetralin as solvent has been investigated.
This investigation differs from others on this subject reported in the literature mainly in the sampling methods employed.
Because of the methods previously employed, effects of heating to reaction temperature and cooling to ambient conditions were not excluded; this complicated an investigation into the kinetics of coal hydrogenation.
In the present investigation samples were withdrawn from the reactor after reaction temperature and pressure had been reached. It is concluded that simple series or parallel reactions suggested in the literature for the hydrogenation of coal are oversimplified mechanisms.

Use of asphaltene instead of the parent coal as the starting material for hydrogenolysis makes it easier to discuss the reaction mechanism, because the mean chemical structures of both reactant and products can be deduced from structural analysis. In this study asphaltene from Japanese Akabira coal
