METHOD OF PRODUCING PITCH FROM BITUMINOUS COAL BY THERMAL DISSOLUTION IN MIXTURE OF ANTHRACENE FRACTION AND HEAVY FRACTION OF LIQUID PRODUCT OF PYROLYSIS OF INDUSTRIAL RUBBER ARTICLES Russian patent published in 2024 - IPC C10G1/04 

Abstract RU 2825573 C1

FIELD: liquefaction of solid combustible minerals.

SUBSTANCE: invention can be used in processing brown and bituminous coals. Invention relates to a method of producing pitch from bituminous coal by thermal dissolution in a solvent, involving conversion of bituminous coal into pitch during thermal dissolution of coals. Solvent used is a mixture of an anthracene fraction and a heavy fraction of a liquid product of pyrolysis of industrial rubber articles in a percentage ratio of 50/50, at optimum weight ratio of coal to solvent—60/40 at temperature in reactor—400 °C.

EFFECT: reduced power consumption, reduced amount of initial components, reduced quantitative content of anthracene fraction.
