FIELD: process engineering.
SUBSTANCE: invention relates to cocking and metallurgy and may be used in production of structural graphite. Hydrocarbon stock is processed by aromatic solvent. Phase separation is made by extraction in apparatus with closed circuit of aromatic solvent circulation in counter-flow conditions at solvent boiling point and atmospheric pressure for 5 to 60 min. Prior to drying, mesomorphic-phase carbon powder is separated at cyclone apparatus at 0.5 to 2 atm.
EFFECT: stabilisation of carbon material with respect to amount of volatile components and ruling out composition shrinkage in thermal treatment.
