Abstract

Coal pitch has a wide range of applications: as a binder in electrode produc? tion, production of carbon graphite products, as raw materials for the pro? duction of carbon fibers, etc. One of the main characteristics of the quality of coal pitch is its fractional composition. Studies have been carried out on the production of coal pitch by distillation of coal tar at atmospheric pressure. During the distillation of the resin, its fractional composition was determined. The yield of coal pitch was 54%. The fractional composition and ash content were determined for the resulting pitch sample. Based on the results of the study, an assessment was made of the possibility of using the resulting pitch for the production of carbon fibers and in electrode production.

Keywords
