【 摘 要 】

Change in group composition of sulfur compounds and structural group composition of the diesel fractions in the course of hydrotreating is presented in the paper. The removal degree of sulfur compounds is shown to comprise 95.8% rel. The homologs of benzothiophenes are removed for 93.9% rel., ones of the dibenzothiophenes are for 90.7% rel. A considerable change in group composition of diesel fraction is established in the course of hydrotreating. Hydrogenation degree of aromatic hydrocarbons is 24.4% wt., the amount of saturated hydrocarbons has increased by 20.4% wt.
