ABSTRACT:
A fibrous carbon is prepared by dissolving coal in a hydrocarbon solvent by heating under hydrogen pressure, by subjecting to melt spinning a solvent-refined coal obtained by successively removing insoluble residues and the solvent from the resultant solution, by making the fiber thus obtained non-fusible, and then by subjecting same to carbonization. The melt spinning may be effected by mixing a highly aromatic bituminous substance with the solvent refined coal. Alternatively, the solvent-refined coal may be pretreated prior to melt spinning by extracting it with a non-aromatic solvent to remove soluble components therefrom.
