Abstract
The chemical composition of the distillate fractions with boiling points of to 180, 180–230, and 230–280°C separated from undehydrated coal tar from OAO Altai-Koks was studied by gas chromatography-mass spectrometry. A list of identified aromatic compounds (including N-, O-, and S-containing compounds) and their alkyl derivatives is given. It was found that, upon the complete processing of tar with the recirculation of residual raw materials at the stage of coking and its hydrogenation refining in the presence of suspended Mo- and Ni-containing catalysts and a hydrogen donor (tetralin), the yields of chemical products were the following (wt %): coke, 50–55; absorption oil, 9–12; benzene, naphthalene, tetralin, dimethylnaphthalenes, and other hydrocarbons, 25–30; BTX fraction 4–5; and C1-C4 and CO2, 10–12.
