Popis:	The hydrogenation process of coal distillates with bp 180–360°C in the presence of Mo- and Co-containing catalysts supported on the surface of skeletal nickel (Raney Ni) was studied. It was established that, in the presence of a catalyst containing 5% Mo/Ni-Re + 7% Co/Ni-Re at a pressure of 10 MPa, a temperature of 400°C, and a feed space velocity of 1.0 h–1, phenols and nitrogen bases were completely removed; sulfur and unsaturated compounds were hydrogenated by 95.4 and 94.7%, respectively; and aromatic hydrocarbons were hydrogenated by 69.7%. The hydrofined distillate fractions with bp 180–360°C meet the requirements of GOST [State Standard] R 52368-2005 (Russia) and the EN 590-2004 EU standard for low-sulfur diesel fuel in terms of their physicochemical and operational properties, and hydrotreated gasoline can be used as a component of low-octane gasoline.
