    摘要： A novel carbonaceous pitch which is optically isotropic in nature and which turns into optically anisotropic when shear forces are applied thereto. The carbonaceous pitch may be obtained by hydrogenating the mesophase of a mesophase pitch to the extent that the mesophase is rendered soluble in quinoline. The carbonaceous pitch is useful as a binder and an impregnator and as a precursor material for a highly oriented, high-strength and high-modulus carbon fiber, needle coke or the like carbonaceous materials.

    摘要： A process for the preparation of carbon fibers, including the steps of:subjecting a raw material oil to thermal cracking conditions at a temperature of between 400.degree. to 500.degree. C. while removing cracked, light hydrocarbon components to obtain a pitch product containing at least 5 weight % of mesophase and not more than 10 weight % of light hydrocarbon components with a boiling point at 60 mmHg (absolute) of 300.degree. C. or less and having a softening point of between 140.degree. and 220.degree. C., the raw material oil having a boiling point of at least 500.degree. C. and containing at least 30 weight % of a residual oil which has a boiling point of at least 500.degree. C. and a metal content of at least 200 weight ppm and which is derived from a napthene base and/or intermediate base petroleum crude;removing the mesophase having a particle size of more than 10 .mu.m from the pitch product to obtain a substantially mesophase-free carbonaceous pitch;spinning the substantially mesophase-free pitch into fibers;rendering the spun fibers infusible; andcarbonizing the infusible fibers.
