FIELD: oil and gas industry. ^ SUBSTANCE: invention refers to crude product obtaining method involving contact of hydrocarbon raw material, where hydrocarbon raw material has viscosity at least of 500 cSt at 37.8C, with hydrogen in presence of one or several catalysts so that total product can be obtained, which includes crude product, where crude product represents liquid mixture at 25C and pressure of 0.101 MPa. At that, crude product has viscosity of not more than 50% of viscosity of hydrocarbon raw material at 37.8C; and where P-factor of hydrocarbon raw material/total product mixture is at least 1.0. At that, viscosity is determined as per ASTM, method D445, and P-factor is determined as per ASTM, method D7060; where at least one catalyst includes metal (metals) of 6-10 groups in combination with carrier and has pore distribution as per sizes with average pore diameter in the range of 50 to 180 A; at that, catalyst includes at least 0.01 gram of aluminium silicate per 1 gram of catalyst; and where contact conditions are controlled at temperature of 370 to 450C, partial hydrogen pressure of not more than 7 MPa and volume rate of liquid supply of at least 0.1 h-1. Invention also refers to catalyst for obtaining crude product. ^ EFFECT: crude product with residue content of not more than 90 percent of residue content in hydrocarbon raw material or reduced viscosity value which represents not more than the half in relation to residue content or viscosity value in hydrocarbon raw material. ^ 14 cl, 27 dwg, 34 ex |
