Hydroprocessing catalyst and support having bidisperse pore structure
This patent describes a catalyst support having a bidisperse micropore size distribution where the micropores have an average pore diameter of less than 600 Angstrom units and being adapted for use as a hydrotreating catalyst support for treating heavy feeds containing large metal bearing molecules comprising a refractory oxide formed particle made of two different micropore size materials having: (a) one small pore material being characterized as having a small micropore region having an average pore diameter of less than 100 Angstrom units; and (b) another material being characterized as having a large micropore region having an average pore diameter (i) which is less than 600 Angstrom units, (ii) which is equal to or larger than 100 Angstrom units, and (iii) which is much larger than the average diameter of the metal bearing molecules in a heavy feed to be processed; the pore volume of the large micropore region comprising 10 to 90% of the total pore volume; and the pore volume of the small micropore region comprising 10 to 90% of the total pore volume.
