Abstract
The article discusses the process of obtaining coal tar by atmospheric distillation of coal tar. Coal tar produced by PJSC "Koks" was used as a feedstock. The studies were carried out by varying the final temperature of the cubic residue in the flask in the range of 400-430 ° C. For the obtained samples of coal tar, their main qualitative characteristics were determined. Based on the obtained research results, the regularities of the influence of the temperature of the coal tar distillation process on the qualitative characteristics of the obtained pitches were revealed. Based on the results of the work performed, an assessment of the suitability of the obtained coal pitch samples for use as raw materials in the electrode industry and in the production of carbon fibers is given.
Keywords
Coal tar, coal pitch, atmospheric distillation, electrode production, carbon fiber.
