PROCESS FOR PREPARING SULPHIDED CATALYST Russian patent published in 2018 - IPC B01J37/20 B01J23/85 B01J27/49 B01J27/51 C10G45/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a process for the preparation of a sulphided catalyst comprising steps of: (a) treating a catalyst carrier with one or more Group VIB metal components, one or more Group VIII metal components and a glycolic acid ethoxylate ether compound according to the formula: R-(CH₂)_x-CH₂-O-[-(CH₂)₂-O]_m-CH₂-COOH (I), in which R is a hydrocarbyl group having from 5 to 20 carbon atoms, x is in the range of 1 to 15, and m is in the range of 1 to 10, and the molar ratio of compound (I) to the Group VIB and Group VIII metals is from at least 0.01: 1 to 1: 0.01; (b) drying the treated catalyst carrier at a temperature of at most 200°C to form a dried impregnated carrier; and (c) sulphiding the dried impregnated carrier to obtain a sulphided catalyst. Invention also relates to a process for hydrotreating a sulphur-containing hydrocarbon feedstock.

EFFECT: technical result consists in improving hydrotreatment activity.
