Abstract
A solid fuel in which an oil mixture containing a heavy oil fraction and a solvent fraction is incorporated in fine pores of a porous coal. The improved porous coal is produced by mixing an oil mixture containing a heavy oil fraction and a solvent fraction with a porous coal to obtain a starting slurry, heating the starting slurry to dewater the porous coal, and incorporate, at the same time, the oil mixture into the fine pores of the porous coal and then subjecting the treated slurry to solid-liquid separation.
