摘要
FIELD: petroleum processing and petrochemistry.;SUBSTANCE: catalytic system is prepared by consecutively charging into reactor alumino-cobalt and alumino-nickel-molybdenum catalysts containing 12.0-25.0% molybdenum oxide, 3,0-6.0% nickel oxide, and 3.0-6.9% cobalt oxide provided that alumino-cobalt and alumino-nickel-molybdenum catalysts are charged at ratio between 1.0:0.1 and 0.1:1.0, preparation of catalysts employs mixture of aluminum hydroxide and/or oxide powders, to which acids are added to pH 1-5. More specifically, aluminum hydroxide powder mixture utilized is a product of thermochemical activation of gibbsite and pseudoboehmite AlOOH and content of pseudoboehmite in mixture is at least 70%, and aluminum oxide powder mixture utilized comprises powders of γ-Al2O3 with particle size up to 50 μm and up to 50-200 μm taken at ratio from 5:1 to 2:5, or γ-Al2O3 powders with particle size up to 50 μm, 50-200 μm, and up to 200-400 μm taken at ratio between 1:8:1 and 3:6:1.;EFFECT: method of preparing catalytic systems for large-scale high-sulfur hydrocarbon feedstock hydrofining processes is provided allowing production of products with desired levels of residual sulfur and polycyclic aromatic hydrocarbons.;4 tbl, 3 ex
