Abstract

Studies have been conducted on the production of coal pitch by atmospheric distillation of coal tar. For the obtained pitch samples, the qualitative characteristics were determined, which are the main ones for the use of pitch as a binder in electrode production in accordance with GOST 10200-2017 “Coal-fired electrode pitch. Technical specifications”. One of the most important characteristics of the electrode pitch is the coke number. The influence of the temperature regime of atmospheric distillation of coal tar and the time of isothermal exposure of pitch on the coke number of pitch was studied. The relationship between the coke number of pitch and its softening temperature, group composition, and the release of volatile substances from pitch has been revealed.

Keywords

Coal tar, coal pitch, atmospheric distillation, electrode production.
