Abstract
Abstract A hydrocarbon conversion process suitable for the conversion of heavy hydrocarbon oils containing large amounts of metallic contaminants, such as petroleum residua, utilizes a catalyst comprising an inroganic oxide gel matrix comprising a major amount of silica, and minor amounts of zirconia and alumina, from about 15 to about 40 weight percent of an adsorbent such as bulk alumina, and a crystalline aluminosilicate zeolite.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
149 words
A process for the conversion of a hydrocarbon oil, which comprises: contacting said oil at hydrocarbon conversion conditions with a catalyst comprising (1) from 3 to about 16 weight percent of a crystalline aluminosilicate zeolite, (2) from about 50 to about 85 weight percent of an inorganic oxide gel component, said inorganic oxide gel comprising a major amount of silica, a minor amount of zirconia and a minor amount of alumina, and (3) from about 15 to about 40 weight percent of a porous substantially inert inorganic oxide adsorbent having a surface area greater than about 200 square meters per gram and having at least 0.2 cubic centimeter per gram of its pore volume in pores ranging in diameter from about 90 to about 200 Angstroms, said catalyst having at least 0.4 cubic centimeter per gram of its pore volume in pores of greater than 90 Angstroms in diameter.
Claim 2
Dependent Claim
149 words
A process for the conversion of a hydrocarbon oil, which comprises: contacting said oil at hydrocarbon conversion conditions with a catalyst comprising (1) from 3 to about 16 weight percent of a crystalline aluminosilicate zeolite, (2) from about 50 to about 85 weight percent of an inorganic oxide gel component, said inorganic oxide gel comprising a major amount of silica, a minor amount of zirconia and a minor amount of alumina, and (3) from about 15 to about 40 weight percent of a porous substantially inert inorganic oxide adsorbent having a surface area greater than about 200 square meters per gram and having at least 0.2 cubic centimeter per gram of its pore volume in pores ranging in diameter from about 90 to about 200 Angstroms, said catalyst having at least 0.4 cubic centimeter per gram of its pore volume in pores of greater than 90 Angstroms in diameter.
