FIELD: coal industry.
SUBSTANCE: invention provides mixture of coal-tar pitch with water, catalyst, and additional components. Mixture is then hydrogenised to form hydrogenate, which is separated into liquid fraction and sediment. The former is distilled together with recycle to produce light distillate fractions and coke-making material. This material is subjected to coking to produce needle-shaped coke, whereas light distillate fractions are hydrogenised to give hydrogen donor. Above-mentioned additional components are hydrogenate separation sediment and hydrogen donor, and recycle is, in particular, coking distillate.
EFFECT: extended processing of coal-tar pitch into high-quality coke and increased yield of low-boiling fractions.
