Claims
- 1. A catalyst mixture comprising a first catalyst composition comprising a porous refractory inorganic oxide wherein said first catalyst composition possesses a pore volume of less than about 0.10 cc/g in pores having a diameter greater than about 200 Angstroms, a pore volume of less than about 0.02 cc/g in pores having a diameter greater than about 800 Angstroms, and a maximum average mesopore diameter of about 130 Angstroms; and a second catalyst composition comprising a porous refractory inorganic oxide wherein said second composition possesses a pore volume of greater than about 0.07 cc/g in pores having a diameter greater than about 800 Angstroms.
- 2. The catalyst mixture of claim 1 wherein said first catalyst composition possesses an average mesopore diameter of about 60 to about 120 Angstroms.
- 3. The catalyst mixture of claim 1 wherein said first catalyst composition possesses an average mesopore diameter of about 80 to about 100 Angstroms and a pore volume of less than about 0.05 cc/g in pores having a diameter greater than about 200 Angstroms.
- 4. The catalyst mixture of claim 1 wherein said second catalyst composition possesses an average mesopore diameter of about 60 to about 200 Angstroms and a pore volume of greater than about 0.1 cc/g in pores having diameters greater than about 800 Angstroms.
- 5. The catalyst mixture of claim 2 wherein said second catalyst composition possesses an average mescopore diameter of about 60 to about 200 Angstroms and a pore volume of greater than about 0.1 cc/g in pores having diameters greater than about 800 Angstroms.
- 6. The catalyst of claim 3 wherein said second catalyst composition possesses an average mesopore diameter of about 60 to about 200 Angstroms and a pore volume of greater than about 0.1 cc/g in pores having diameters greater than about 800 Angstroms.
- 7. The catalyst mixture of claim 1 wherein said second catalyst composition possesses an average mesopore diameter of about 150 to about 180 Angstroms and a pore volume of greater than about 0.1 cc/g in pores having a diameter greater than about 1200 Angstroms.
- 8. The catalyst mixture of claim 2 wherein said second catalyst composition possesses an average mesopore diameter of about 150 to about 180 Angstroms and a pore volume of greater than about 0.1 cc/g in pores having a diameter greater than about 1200 Angstroms.
- 9. The catalyst mixture of claim 3 wherein said second catalyst composition possesses an average mesopore diameter of about 150 to about 180 Angstroms and a pore volume of greater than about 0.1 cc/g in pores having a diameter greater than about 1200 Angstroms.
- 10. The catalyst mixture of claim 1 wherein said first composition is present in an amount ranging from about 10 to about 90 volume % based on the total amount of said catalyst mixture.
- 11. The catalyst mixture of claim 1 wherein said first composition is present in an amount ranging from about 20 to about 80 volume % based on the total amount of said catalyst mixture.
- 12. The catalyst mixture of claim 1 wherein said first composition is present in an amount ranging from about 50 to about 70 volume % based on the total amount of said catalyst mixture.
- 13. The catalyst mixture of claim 1 wherein said catalyst mixture comprises a hydrogenation component selected from the group consisting of Group VIB metal Group VIII metal, and phosphorus.
