Abstract

One of the most important quality characteristics of coal tar and coal pitches is the content of substances insoluble in quinoline (?1 fractions).Quality studies of coal tar produced by PJSC “Koks” and samples of coal pitches obtained from it were carried out. Coal tar pakes were obtained by atmospheric and vacuum distillation of resin. The final distillation temperature of the resin (the temperature of the cubic residue) was 400 ° C. The obtained samples of coal tar were studied to determine their qualitative characteristics: softening temperature, ash content, yield of volatile substances, content of substances insoluble in toluene, content of substances insoluble in quinoline. The influence of coal tar distillation conditions on the ?1 fraction content in the resulting coal pitches has been studied.

Keywords

Coal tar, coal pitch, electrode production, carbon fiber, resin distillation.
