Abstract

The article discusses the results of scientific research on the production of coal pitch by atmospheric distillation of coal tar of coke chemical pro? duction of PJSC Coke. The qualitative characteristics of the initial coal tar (density, ash content, water content, etc.) were investigated. During the distillation of coal tar, the following fractions were isolated: light, phenolic, naphthalene, absorbent, anthracene and coal pitch. The yield of the sand fraction was 54% by weight. Analysis of the results of studies of the quality of coal pitch obtained during atmospheric distillation of resin showed that this pitch meets the requirements for electrode pitches in most indicators (according to GOST 10200-2017). To reduce the content of volatile substances in coal tar requires additional heat treatment at temperatures above 360 C.

Keywords
