FIELD: oil-and-gas industry.SUBSTANCE: invention relates to production of super low-sulphur diesel fractions by hydrorefining at higher temperatures and pressure at alumocobalt (or nickel) molybdenum catalysts. Said hydrorefining is conducted 360-400°C, at least 30 atm, weight hour space velocity not over 1h, hydrogen-to-stock ratio of at least 300 nm/m.Catalyst is obtained by adsorption of active components from low-percentage water solution of salts on the surface of aluminium oxide carriers in two steps with intermediate drying: MoO, is obtained at first step, CoO(NiO)·MoOor CoO(NiO) is obtained at second step.EFFECT: production of super low-sulphur diesel fractions.2 cl, 2 dwg, 7 tbl, 3 ex |
