FIELD: hydrocarbons.

SUBSTANCE: invention relates to a method for processing heavy hydrocarbon feedstock, including the successive passage of feedstock in the presence of hydrogen, supplied under pressure of 8-20 MPa, through a fixed catalyst bed 1 comprising aluminium oxide as a carrier, and calcium and/or magnesium compounds as an active component, having macropores with a regular spatial structure, through catalyst 2 comprising aluminium oxide as a carrier, and compounds of cobalt and/or nickel and/or molybdenum and/or tungsten as an active component, having macropores with a regular spatial structure, through catalyst 3 obtained by sulfiding a composition comprising an active ingredient and a carrier. The active component consists of a heteropoly compound containing at least one of the following compounds of the series [Co₂Mo₁₀O₃8H₄]^6-, Co₃[PMo₁₂O₄₀]², Ni₃[PMo₁₂O₄₀]², [Co(OH)₆Mo₆O₁₈]^3-, [Ni(OH)₆Mo₆O₁₈]^2-, [Ni₂Mo₁₀O₃₈H₄]^6-, [Co(OH)₆W₆O₁₈]^3-, [PMo_nW_12-nO₄₀]^3- (where n = 1-11), [PVnMo_12-nO₄₀]^(3+n)- (where n = 1-4), Mo₁₂O₃₀(OH)₁₀H₂[Co(H₂O)³]₄ or a mixture thereof and an organic additive, whereas the carrier is alumina, silicon oxide, zeolite, aluminosilicate, porous aluminophosphate, porous silicoaluminophosphate and their combination, having a regular spatial macropore structure. Further separation of gaseous products with the possibility of separating into separate oil products.

EFFECT: simultaneous involvement of raw materials in the processing without restrictions on viscosity and density, on the content of sulphur, metals and the production of oil products suitable for further processing to obtain commercial oil products without additional operations and the formation of non-recyclable residues.
