Patent ID: 8877671

Claim:
A method for preparing a hydroprocessing catalyst comprising: (I) providing at least the following components: (A) at least one calcined foraminous carrier having a water pore volume; (B) catalytically active metals useful in hydroprocessing hydrocarbons, said metals in the form of at least one component providing at least one metal from Group VIB of the periodic table and at least one component providing at least one metal from Group VIII of the periodic table; (C) at least one chelate; (D) water in a quantity sufficient to form a solution or dispersion comprising said catalytically active metals and said at least one chelate; and (E) optionally, at least one phosphorus-containing acidic component; (II) contacting said components (I)(A) with said solution or dispersion comprising (I)(B), (I)(C), (I)(D) and optionally (I)(E) for a time and at a temperature sufficient to form a mixture and to impregnate said carrier with a suitable amount of said components (I)(B) and (I)(C) and optionally (I)(E); (III) to the extent that the volume of said solution or dispersion equals or exceeds the water pore volume of said carrier separating said impregnated carrier from said excess solution or dispersion; and (IV) drying said impregnated carrier by heating to a temperature of 400° F. to 420° F. (204.4° C. to 215.5° C.) for a period of time less than 1 hour so that no substantial decomposition of said at least one chelate is caused, thereby forming said hydroprocessing catalyst.
