The structural parameters of the average pitch molecules have been compared based on the 1H and 13C NMR spectra. It was shown that, in terms of chemical composition and empirical properties including carcinogen content, the extractive pitches resemble blended pitch sample, the structural parameters being close to commercial coaltar pitch sample. The average pitch molecule of extractive pitches was composed of predominantly aromatic nuclei with rather pericondensed structure

ΡΡΠ°ΠΊΡΠΈΠΉCarried out a comprehensive study of individual and group component composition, physical and
chemical parameters of liquid products formed during coking tar of Β«Achinsk RefineryΒ» at various
temperatures and pressures coking in order to assess the possibility of involving them in the range
of marketable products. Special attention is paid to the quantitative indicators of the hydrocarbon
composition of distillate fraction, as well as evaluating the content of general and mercaptan sulfur.
Revealed regularities of changes in the composition and properties of narrow fractions of liquid products
of coking on the technological parameters of the process. Developed preliminary recommendations
for the achievement of the maximum rate of output and optimal hydrocarbon composition of distillate
fraction
