摘要： A raw material pitch for carbon fiber production, with which carbon fiber excellent in tensile strength can be produced at relatively low costs, is provided. The raw material pitch is obtained from coal, is a pitch for producing carbon fiber by melt spinning, and contains oxygen in a content of 1.0% by mass or more and a toluene-soluble component in a content of 20% by mass or more. The coal is preferably bituminous coal or sub-bituminous coal. The raw material pitch is preferably prepared by subjecting a solvent-soluble component separated from a thermal decomposition product of coal in a solvent by a solvent extraction treatment at a temperature of less than 300° C. to a heat treatment at a temperature of 150° C. or more.

摘要： This method for producing a carbon material includes: a step of mixing an ashless coal, which is obtained by subjecting coal to a solvent extraction treatment, with an ashless coal coke, which is obtained by carbonizing an ashless coal; a step of heating and molding the obtained mixture; and a step of carbonizing the obtained molded body. In addition, the obtained carbon material contains ashless coal and has an optically anisotropic structure in which the proportion of the structure that is a coarse-grained mosaic or finer is 90% or higher.

摘要： A production apparatus of an ashless coal includes a preheater, an extraction tank, a feed pipe, a solid-liquid separator and a solvent separator. The preheater heats a solvent. The extraction tank extracts a coal component soluble in the solvent from a slurry including a mixture of a coal and the solvent heated by the preheater. The coal feeding unit feeds the coal to the feed pipe by pressuring a feed part to the feed pipe such that the solvent does not flow back. The solid-liquid separator separates a solution part containing the coal component from the slurry. The solvent separator evaporates and separates the solvent from the solution part to obtain an ashless coal.
