FIELD: chemistry.

SUBSTANCE: invention relates to a method for preparing a hydrotreating catalyst and to a method for hydrotreating a sulfur-containing hydrocarbon feedstock. Said method for preparing a hydrotreating catalyst is that the alumina carrier is impregnated with a solution containing from 14 to up to 40 wt. % of molybdenum, from 2 to up to 12 wt. % of nickel, from 1.5 to 3.5 wt. % of phosphorus and gluconic acid in an amount of from 1 to 60 wt. % relative to the weight of the carrier. If necessary, the treated carrier is dried at a temperature of from 40 to 200 °C. Next, the treated carrier is burned at a temperature of from 200 to 650 °C. Further, the ratio of the weight of gluconic acid to the total weight of nickel and molybdenum, deposited on the carrier, is from 0.7 to 1.5 before firing. Gluconic acid is used in the form of gluconic acid, or a salt of gluconic acid, or a gluconic acid ester. As phosphorus compounds, orthophosphoric acid is used. Said method for hydrotreating a sulfur-containing hydrocarbon feedstock consists in bringing the hydrocarbon feedstock into contact with the above catalyst at a partial pressure of hydrogen of from 1 to 70 bar and a temperature of from 200 to 420 °C.

EFFECT: invention allows to obtain a hydrotreating catalyst with high activity.
