FIELD: chemistry.
SUBSTANCE: method for obtaining oil-coal tar pitch from resin includes resin distillation with obtaining non-distillable distillation residue. Obtained distillation residue is subjected to thermal exposure and oxidation with air oxygen to obtain pitch. As resin used is coal-oil resin, obtained in coking of mixture of coal charge with oil semi-coke with output of volatile substances from 14 to 25%, with content of oil semi-coke in coked mixture 10-15 wt %.
EFFECT: invention makes it possible to extend raw material base for obtaining oil-coke tar pitch, and simplify method of thereof obtaining.
