Thermal treated coal which has a water content of not more than 10%, which has pores with an oil adsorbed onto and impregnated into the pore surface, and which is decarboxylated and dehydrated to have a reduced porosity is provided. In its manufacture, porous coal and an oil are mixed to prepare a slurry, and the slurry is heated for effecting slurry dewatering. During the slurry dewatering, oil is adsorbed onto the surface of the pores of the porous coal. Subsequently, the slurry is heated for refining, followed by a solid-liquid separation at the final stage. |
