Process for preparing a hydrotreating catalyst comprising of from 5 wt % to 50 wt % of molybdenum, of from 0.5 wt % to 20 wt % of nickel and of from 0 to 5 wt % of phosphorus, all based on total dry weight of catalyst, which process comprises (a) treating alumina carrier with molybdenum and nickel and of from 1 to 60% wt of gluconic acid, based on weight of carrier, and optionally phosphorus, (b) optionally drying the treated carrier at a temperature of from 40 to 200&#xb0; C., and (c) calcining the treated and optionally dried carrier at a temperature of from 200 to 650&#xb0; C. to obtain the calcined treated carrier.

Process for preparing a hydrotreating catalyst

Process for preparing a hydrotreating catalyst comprising of from 5 wt % to 50 wt % of molybdenum, of from 0.5 wt % to 20 wt % of cobalt, and of from 0 to 5 wt % of phosphorus, all based on total dry weight of catalyst, which process comprises (a) treating a nickel containing carrier with molybdenum, cobalt and of from 1 to 60% wt of gluconic acid, based on weight of carrier, and optionally phosphorus, (b) optionally drying the treated carrier at a temperature of from 40 to 200&#xb0; C., and (c) calcining the treated and optionally dried carrier at a temperature of from 200 to 650&#xb0; C. to obtain the calcined treated carrier.

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&#x2014;(CH)&#x2014;CH&#x2014;O&#x2014;[&#x2014;(CH)&#x2014;O&#x2014;]&#x2014;CH&#x2014;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&#xb0; C. to form a dried impregnated carrier; and (c) sulphiding the dried impregnated carrier to obtain a sulphided catalyst.
