Carried out a comprehensive study of individual and group component composition, physico-chemical parameters of liquid products produced during the coking of tar "Achinsk Refinery" at different temperatures and pressures coker to assess the possibility of their involvement in a range of commercial products. Particular attention is given to quantitative indicators of hydrocarbon fractions coker distillates, as well as evaluating the overall content and mercaptan sulfur. The regularities of changes in the composition and properties of narrow fractions of liquid products from the coking process parameters. Preliminary recommendations are designed to achieve maximum performance and optimum output of the hydrocarbon composition of the distillate fractions.
