A hydroprocessing catalyst composition that comprises a shaped support that is formed from a mixture of inorganic oxide powder and catalyst fines and wherein the shaped support has incorporated therein at least one metal component, a chelating agent and a polar additive. The hydroprocessing catalyst composition is prepared by incorporating into the shaped support a metal component, a chelating agent and a polar additive. The hydroprocessing catalyst composition has particular application in the catalytic hydroprocessing of petroleum derived feedstocks.

1. A method of making a catalyst composition, wherein said method comprises: forming a shaped support comprising an inorganic oxide powder and catalyst fines, wherein said catalyst fines are present in said shaped support in an amount in the range up to 50 wt % of said shaped support, wherein the fraction of the total pore volume of the shaped support that is contained in macropores exceeds 10%, and wherein said shaped support is dried and calcined;incorporating a chelating agent and a metal-containing solution into said shaped support to provide a chelant treated metal-incorporated support;drying said chelant treated metal-incorporated support so as to provide a dried chelant treated metal-incorporated support having a volatiles content in the range of from 1 to 20 wt % LOI thereby creating an available pore volume;incorporating a polar additive into said dried chelant treated metal-incorporated support in an amount such that at least 75% of the available pore volume of said dried chelant treated metal-incorporated support is filled with said polar additive, to thereby provide an additive impregnated composition. 2. A method as recited in claim 1, wherein said dried chelate treated metal-incorporated support has a volatiles content in the range of from 3 to 15 wt % LOI into which said polar additive is incorporated to provide said additive impregnated composition. 3. A method as recited in claim 2, wherein said step of drying said-chelate treated metal-incorporated support is conducted at a drying temperature not to exceed 400° C. 4. A method as recited in claim 1, wherein said chelating agent is incorporated into said shaped support either prior to the incorporation of said metal-containing solution into said shaped support or in combination with or as a component of said metal-containing solution. 5. A method as recited in claim 4, wherein said chelating agent is incorporated into said shaped support, prior to the incorporation of said metal-containing solution into said shaped support, and thereafter drying said shaped support with said chelating agent incorporated therein to provide said shaped support with said chelating agent and having a volatiles content in the range of from 1 to 20 wt % LOI. 6. A method as recited in claim 5, wherein said step of drying said metal-incorporated support is conducted at a first drying temperature not to exceed 400° C., and said step of drying said shaped support with said chelating agent incorporated therein is conducted at a second drying temperature not to exceed 400° C. 7. A method as recited in claim 1, wherein said chelating agent is selected from the group of compounds consisting of aminocarboxylic acids, polyamines, aminoalcohols, oximes, and polyethyleneimines. 8. A method as recited in claim 1, wherein said polar additive is a heterocompound having polarity and a dipole moment of at least 0.45. 9. A method as recited in claim 8, wherein the shaped support containing said catalyst fines has a pore structure such that at least 20% of its total pore volume is contained in macropores. 10. A method as recited in claim 1, wherein said additive impregnated composition comprises a Group 9 or Group 10 metal component selected from the group consisting of cobalt and nickel present in an amount in the range of from 0.5 wt. % to 20 wt. %, and a Group 6 metal component selected from the group consisting of molybdenum and tungsten present in an amount in the range of from 5 wt. % to 50 wt. %, wherein the weight percents are based on the weight of the dry support material with the metal component as the element regardless of its actual form. 11. A method as recited in claim 1, wherein said shaped support comprises a porous refractory oxide selected from the group of refractory oxides consisting of silica, alumina, titania, zirconia, silica-alumina, silica-titania, silica-zirconia, titania-alumina, zirconia-alumina, silica-titania and combinations of two or more thereof; and wherein said shaped support has a surface area (as determined by the BET method) in the range of from 50 m2/g to 450 m2/g, a mean pore diameter in the range of from 50 to 200 angstroms (Å), and a total pore volume exceeding 0.55 cc/g. 12. A method as recited in claim 1, wherein at least 80% of the available pore volume of said dried chelant treated metal-incorporated support is filled with said polar additive. 13. A method as recited in claim 12, wherein the polar additive is dimethyl formamide and at least 90% of the available pore volume of said dried metal-incorporated support is filled with said polar additive. 14. A method as recited in claim 12, wherein the polar additive is a mixture of dimethyl formamide and hexadecylamine. 15. A method as recited in claim 14 wherein the chelating agent is diethylenetriaminepentaacetic acid. 16. A method as recited in claim 1, wherein the shaped support containing said catalyst fines has a pore structure such that at least 15% of its total pore volume is contained in macropores.
