FIELD: mining.
SUBSTANCE: invention relates to the field of liquefaction of solid combustible minerals; it can be used in processing of brown and hard coal, in particular, it relates to a method for obtainment of pitch. The method is carried out by thermal dissolution of hard coal in an anthracene fraction at a mass ratio of hard coal to a solvent of 70/30 and a reactor temperature of 400°C.
EFFECT: reduction in energy consumption due to simplification of a technology of obtainment of products with given properties, increase in safety of production, increase in ecological safety by reduction in content of compounds of increased ecological danger, including benz(a)pyrene.
