CATALYST, METHOD OF PRODUCING CARRIER, METHOD OF PRODUCING CATALYST AND METHOD OF HYDROFINING HYDROCARBON FEEDSTOCK Russian patent published in 2017 - IPC B01J32/00 B01J21/04 B01J23/882 B01J23/883 B01J37/02 C10G45/08 

FIELD: chemistry.

SUBSTANCE: carrier of producing catalysts is described, which is modified γ-Al₂O₃ having a pore volume of 0.3-0.95 cm³/g, a specific surface area of 170-280 m²/g, an average pore diameter of 7-22 nm, and a mechanical strength of 2.0-2.5 kg/mm. γ-Al₂O₃ is modified with additives of the d-metal elements Ti or Zr, or V, or Cr, or Mn, or Cu, Zn, or by impregnating an aqueous solution of citrate or tartrate of corresponding metal with subsequent drying at a temperature of 120°C and by calcining at 550°C. A catalyst of hydrofining a hydrocarbon feedstock is also described, containing, wt %: 0-20 MoO_3, and/or 0-24 WO₃, 3-5 NiO or CoO, the rest - the carrier, method of producing a catalyst and method of hydrofining a hydrocarbon material.

EFFECT: producing catalysts of hydrofining with high activity in the hydrodesulfurization of hydrocarbon feedstock.
