Patent ID: 7605107

Claim:
A method for preparing a sulfided catalyst composition, which method comprises: (a) impregnating an inorganic catalyst support with an aqueous solution containing (i) a salt of a Group VIII metal selected from Co and Ni, (ii) a salt of a Group VI metal selected from Mo and W, and (iii) an effective amount of an organic agent selected from amino alcohols and amino acids; (b) drying said impregnated catalyst support to remove substantially all water, thereby resulting in a metal-organic component on support catalyst precursor; (c) heating said substantially dried catalyst precursor in a heating step wherein the temperature is increased to above 200° C. but to less than about 325° C., in an oxygen-containing atmosphere wherein about 20 wt. % to about 80 wt. % of the organic portion is oxidized; (d) sulfiding said partially oxidized catalyst precursor at sulfiding conditions in the presence of a sulfiding agent, thereby resulting in a sulfided catalyst composition.
