Abstract
Abstract A demetalation and desulfurization catalyst for metal and sulfur containing petroleum oils, e.g., residua containing hydrocarbon components, comprising a hydrogenating component composited on a refractory base, e.g., alumina, having a substantially higher pore volume and more pore volume distributed within the 0-100 ANGSTROM diameter range than such previously known catalysts and method of using same; said catalyst possesses superior aging characteristics.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
120 words
A hydrometalation-desulfurization catalyst comprising a hydrogenating component which comprises a Group VI-B metal oxide or sulfide and a Group VIII metal oxide or sulfide composited with a porous alumina base, said catalyst having at least about 25% of the volume of the pores with a diameter within the range of about 0 to 30 Å, at least about 50% of the volume of the pores with a diameter within the range of about 0 to 100 Å and further having a pore volume of from about 0.80 to about 0.95 cc/gram and an average pore diameter of about 145 Å to about 170 Å and a surface area of about 180 m 2 /gram to about 220 m 2 /gram.
Claim 2
Dependent Claim
120 words
A hydrometalation-desulfurization catalyst comprising a hydrogenating component which comprises a Group VI-B metal oxide or sulfide and a Group VIII metal oxide or sulfide composited with a porous alumina base, said catalyst having at least about 25% of the volume of the pores with a diameter within the range of about 0 to 30 Å, at least about 50% of the volume of the pores with a diameter within the range of about 0 to 100 Å and further having a pore volume of from about 0.80 to about 0.95 cc/gram and an average pore diameter of about 145 Å to about 170 Å and a surface area of about 180 m 2 /gram to about 220 m 2 /gram.
