Abstract: Heavy oil derived from coal is diluted with organic solvent to a content of less than 10 weight percent of toluene-insoluble material. The mixture is then mixed with a non-aromatic solvent in a ratio of 1:3 to 5:1. With slow stirring of the heavy phase at a temperature of between 50.degree. and 200.degree. C., this mixture is separated into a pumpable TI-poor and a pumpable TI-rich fraction under the action of gravity, with a settling-surface load of up to 1 metric ton/m.sup.2 hour. No .beta.-resins are precipitated from these fluid fractions. No tacky, rubber-like sediment is formed from the TI-rich fraction. The fractions are distillatively separated from the solvents, which can be reused. The TI-poor fraction can be used, for example, as a carbon-black oil component or can be processed further to an impregnating agent for carbon shapes. Binders for carbon shapes or cokes are obtained from the TI-rich fraction.

Abstract: A process is described for the production of high grade carbonaceous binders, wherein an aromatic high grade carbonaceous material is produced from 5-40% by weight of reduced or low ash coal or similar carbon containing raw materials by treatment with 20-80% by weight of high-boiling aromatic solvents, derived from coal, and 15-50% by weight of high-boiling aromatic solvents, derived from mineral oil, at temperatures of 300.degree.-420.degree. C. and for a reaction period of 1-4 hours, at a reaction pressure of up to 50 bar, and is optionally freed from low-boiling components.

Abstract: This invention relates to a plasticized coal tar pitch comprising a mixture consisting essentially of about 50 to about 80 weight percent of a coal tar pitch having a softening point of about 40.degree. to about 75.degree. C. (Kramer-Sarnow); and about 50 to about 20 weight percent of a coal tar fraction rich in crystals and having a boiling point of about 350.degree. C. to about 450.degree. C. The mixture is suitable for blending with crude oil bitumen for producing a binder suitable for application to roadways.
