FIELD: process engineering.

SUBSTANCE: invention relates to oil processing, in particular, to production of catalyst for extracting sweet oil fraction to be used in oil processing and petrochemistry. Proposed catalyst including commercial molybdenum disulphide and/or tungsten disulphide, as active components, produced by CBC-method with carrier, a nano-sized pseudo-boehmite, in 20:80 ratio or without, subjected to mechanical and chemical effects, promoter, e.g. nanopowders of 3D-metals (Ni, Co, Fe) produced by physical methods at active component-to-promoter ratio of 70:30 with particle size of smaller than 100 nm, and, additionally, gas-phase nanopowder of Ni in pyrocarbon shell with particle size of smaller than 10 nm in amount of 3 wt % of active component. Invention covers method of producing said catalyst in vertical vibration mill by mechanical and chemical activation of components at vacuum of 10^-5 torr with frequency and amplitude of vibration of 16 Hz and 2 mm, respectively, and activation time of 4-12 h.

EFFECT: higher activity of catalyst, ultralow content of residual sulfur in hydrodesulfuration products.
