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 1to 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 °C, and (c) calcining the treated and optionally dried carrier at a temperature of from 200 to 650 ºC to obtain the calcined treated carrier. |
