FIELD: process engineering.

SUBSTANCE: invention relates to method of producing catalytic composition consisting of, at least, one basic metal of VIII group and, at least, one metal of VIB group. Proposed method comprises the following stages: a) dissolving and mixing salts of precursors in solvent, i.e. water, alcohol represented by methanol, ethanol, propyl alcohol, butanol, and/or water-alcohol mix; b) dissolving organic component and/or surfactant in solvent; c) mixing solutions produced at stages (a) and (b); d) adding basic solution of ammonium hydroxide and/or carbonate to solution of stage (c) to pH 5-14, preferably, to pH 8-12; e) increasing temperature of solution produced at stage (d) to 50-200°C, preferably, to 60-100°C; f) homogenising solution of stage (e); g) crystallizing solution of stage (f) by evaporating the solution; h) filtering or centrifuging crystallised suspension of stage (g) to separate crystals and mother solution in case evaporation is not completed; i) rinsing solid substance produced at stage (h) by sufficient amount of deionised water and/or water-alcohol mix; j) drying solid substance produced at stage (i) at 50-300°C, preferably, at 80-150°C, k) thermal treatment of solid substance produced at stage (j) in inert atmosphere, e.g. nitrogen, helium, argon etc., at 200-1000°C, preferably, at 300-600°C; 1) sulphurising substance produced at stage (i) or (j) in gas flow containing 10 vol. % of carbon sulphide, or hydrocarbon fraction containing, at least, 0.2 wt % of sulfur in hydrogen flow at 200-600°C, preferably, at 250-500°C, and pressure of 1-100 kg/cm². Invention covers also catalytic composition produced as described above.

EFFECT: catalytic composition with high specific activity in hydraulic separation of light and medium fractions.
