Catalyst support and catalysts prepared therefrom

摘要

A supported catalyst useful in processes for chemically refining hydrocarbon feedstocks, the catalyst comprising a metal from Group 6, a metal from Group 8, and optionally phosphorous, wherein the carrier or support, comprises porous alumina comprising: (a) equal to or greater than about 78% to about 95% of TPV in pores having a diameter of less than about 200 Angstroms (A); (b) greater than about 2% to less than about 19% of the TPV in pores having a diameter of about 200 to less than about 1000 A; (c) equal to or greater than 3% to less than 12% of the TPV in pores having a diameter equal to or greater than about 1000 A.

主权项

1. A supported catalyst comprising at least one metal from Group 6, alternatively referred to as Group VIB, of the Periodic Table of the Elements, at least one metal from Groups 8, 9 or 10, alternatively referred to as Group VIII, of the Periodic Table of the Elements, and optionally comprising phosphorous, wherein said metals, and phosphorous when present, are carried on a foraminous carrier or support, said carrier or support having a total pore volume (TPV) of about 0.6 cc/g to about 1.1 cc/g and comprising:
(a) equal to or greater than about 78% to about 95% of TPV in pores having a diameter of less than 200 Angstroms (Å); (b) greater than about 2% to less than about 19% of TPV in pores having a diameter of 200 (Å) to less than 1000 Å; (c) equal to or greater than 3% to less than 12% of TPV in pores having a diameter equal to or greater than 1000 Å; and (d) a pore mode equal to or greater than about 90 Å and less than about 160 Å.
