PROCESS FOR PREPARING A SULPHIDED CATALYST

摘要

The invention provides a process for preparing a sulphided catalyst comprising the 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 (I) R—(CH2)x—CH2—O—[—(CH2)2—O—]m—CH2—COOH (I) wherein R is a hydrocarbyl group containing of from 5 to 20 carbon atoms, x is in the range of from 1 to 15, and m is in the range of from 1 to 10, and wherein the molar ratio of compound (I) to the Group VIB and Group VIII metal content is 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.
