ABSTRACT:
An ashless liquid fuel of good quality is produced by mixing powdery coal with a pitch having a C/H ratio of from 0.90 to 1.20 in an amount of at least 50 parts by weight per 100 parts by weight of the powdery coal, subjecting the mixture to a heat treatment conducted at from 400.degree. to 450.degree. C. and thereafter, removing a solid coagulated material formed in the treated product. The pitch having an atomic ratio C/H in the range from 0.90 to 1.20 is obtained by the heat treatment of a residual oil in the distillation of crude oils.
