Abstract

The article discusses the results of research on the influence of the temperature of the atmospheric vacuum distillation of coal tar on the quality of the resulting coal pitches. Coal tar produced by PJSC “Koks” was used as a feedstock for the production of pitches. During the studies, the final temperature of the cubic residue in the flask varied in the range of 420-440°C. The obtained samples of coal tar were studied to determine their qualitative characteristics and analyzed for compliance with the quality of pitch with the requirements of GOST 10200-2017. The analysis of the research results showed that the quality of the obtained coal pitch samples meets the requirements for electrode baking according to GOST 10200-2017. It was revealed that the temperature of the atmospheric vacuum distillation of coal tar has a significant effect on the quality of the resulting coal pitches.

Keywords
