Catalytic hydrogenation of coal using a shaking type autoclave in the presence of a vehicie and iron-compound catalysts has been carried out for Miike, Minami-ohyubari and Taihelyo coals at higher reaction temperatnre 450℃ and reaction pressure 20.2 MPa, the following results being obtained:　(1) When a very active catalyst was used, the coals were almost converted to ”asphaltene” and ”oil” in the heating up period, and during the reaction period these products were reformed to become mainly lower molecular-weight matter.　(2) When relatively much amount of a disposable catalyst was used, hydrogenation characteristics was simliar to that for the very active catalyst.　(3) It was shown that the shortening of reaction time and the application of the tubular-type reactor with residence time 10-15 min instead of the tank-flow reactor having residence time 60-120 min to the hydrogenation of a coal were possible by using the disposable catalyst that was iron ore or red mud.
