FIELD: metallurgy.
SUBSTANCE: carbonisation product of coal-tar pitch is processed by aromatic solvent. Then, phase separate is executed to obtain the solvent, anisotropic pitch fraction and anisotropic carbon powder by extraction in pendulum -type device including extractor 6 secured at base 1 for continuous pendulum motion. Extractor 6 consists of cylindrical housing with heat-insulation and heating jacket, used solution drain pipe arranged at housing bottom, initial suspension feed pipe arranged at housing cover upper part. Vessel with cylindrical cartridge is arranged inside said housing and secured therein, filter material being secured at perforated bottom, in its circle. Further flushing, filtration and drying are performed in the same device.
EFFECT: higher yield of anisotropic carbon powder.
