CATALYST, METHOD OF PREPARING SAID CATALYST AND PROCESS FOR HYDROFINING HYDROCARBON MATERIAL Russian patent published in 2010 - IPC B01J21/04 B01J27/19 B01J27/24 C10G45/08 

FIELD: chemistry.

SUBSTANCE: described is a catalyst for hydrofining hydrocarbon material having pore volume 0.3-0.7 ml/g, specific surface area 20 - 350 m²/g and average pore diametre 9-13 nm, and containing 20-30 wt % bimetallic complex [M(H₂O)₂(H₂N)₂CO]₂[P₂Mo₅O₂₃]×0.5M(H₂O)₆, which corresponds to content of the following compounds in the catalyst which is annealed at 550°C, in wt %: MoO₃ - 12.0-18.0; MO - 3.0-4.6; P₂O₅ - 2.3-3.6 Al₂O₃ - the rest, where M is Co²⁺ or Ni²⁺ or their mixture. The catalyst is prepared by impregnating and subsequently drying aluminium oxide with a solution of the above mentioned complex. Concentration of the bimetallic compound in the solution is such that there is 20-30 wt % of the bimetallic complex in the catalyst. The process of hydrofining hydrocarbon material is carried out at temperature 320-400°C, pressure 0.5-10 MPa, weight flow rate of material of 0.5-5 h^-1, volume ratio hydrogen/material equal to 100-1000 m³/m³ in the presence of the catalyst described above.

EFFECT: maximum catalyst activity in target reactions taking place when hydrofining hydrocarbon material, thereby obtaining petroleum products with low residual content of sulphur.
