Abstract
Review of the state of the problem connected with the preparation of substitutes for coal-tar pitch for the production high-quality carbon materials is presented. The possibilities of alternative methods of their preparation from petroleum raw material and the products of thermal and thermochemical coal processing are considered. The promising significance of the low-temperature process of coal thermal dissolution under soft conditions for obtaining extractive pitch is demonstrated. A comparison of the chemical composition and technical parameters of the obtained extractive pitch with the industrial coal-tar pitch and petroleum-based pitch is carried out. The obtained extractive pitch is close in composition, molecular structure and technical parameters to coal-tar pitch and petroleum-coal tar pitch. Using extractive pitch as a binder, an experimental sample of anode was manufactured. Its correspondence to the major technical requirements was demonstrated.
