Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
82 words
A process for hydrogen treating a hydrocarbon feed which comprises contacting said feed, at hydrogen treating conditions, with a catalyst comprising shaped catalytic bodies including (1) dispersed rods of fibrous form imogolite and (2) at least one inorganic oxide gel, said gel bonding said rods together in substantially random mutual orientation in said catalytic bodies, at least 40% of the total pore volume in said catalytic bodies being provided by pores with diameters between about 200 Angstrom units and 1,000 Angstrom units.
Claim 2
Dependent Claim
82 words
A process for hydrogen treating a hydrocarbon feed which comprises contacting said feed, at hydrogen treating conditions, with a catalyst comprising shaped catalytic bodies including (1) dispersed rods of fibrous form imogolite and (2) at least one inorganic oxide gel, said gel bonding said rods together in substantially random mutual orientation in said catalytic bodies, at least 40% of the total pore volume in said catalytic bodies being provided by pores with diameters between about 200 Angstrom units and 1,000 Angstrom units.
Claim 3
Dependent Claim
29 words
A process as defined in claim 1 wherein said inorganic oxide gel is present in said composition in an amount between 30 and 50 weight percent of said rods.
Claim 4
Dependent Claim
28 words
A process as defined in claim 1 wherein the average length of said rods is between 2% and 10% of the average diameter of said shaped catalytic bodies.
Claim 5
Dependent Claim
33 words
A process as defined in claim 1 wherein said rods have an average length:diameter ratio between about 5:1 and 100:1, said diameter being the maximum diameter of said rods normal to said length.
Claim 6
Dependent Claim
33 words
A process as defined in claim 1 wherein said catalytic bodies further include from about 0.1 to about 10 weight percent of at least one metal selected from chromium, molybdenum, tungsten and vanadium.
Claim 7
Dependent Claim
32 words
A process as defined in claim 1 wherein said catalytic bodies further include from about 0.1 to about 10 weight percent of at least one metal selected from iron, nickel and cobalt.
Claim 8
Dependent Claim
60 words
A process for hydrodemetalizing a hydrocarbon feed which comprises contacting said feed, at hydrodemetalizing conditions, with a catalyst including (1) dispersed rods of fibrous form imogolite and (2) from 10 to 50 weight percent, based on said rods, of at least one inorganic oxide gel, said gel bonding said rods together in substantially random mutual orientation in said catalytic bodies.
Claim 9
Dependent Claim
60 words
A process for hydrodemetalizing a hydrocarbon feed which comprises contacting said feed, at hydrodemetalizing conditions, with a catalyst including (1) dispersed rods of fibrous form imogolite and (2) from 10 to 50 weight percent, based on said rods, of at least one inorganic oxide gel, said gel bonding said rods together in substantially random mutual orientation in said catalytic bodies.
Claim 10
Dependent Claim
29 words
A process as defined in claim 7 wherein said inorganic oxide gel is present in said composition in an amount between 30 and 50 weight percent of said rods.
Claim 11
Dependent Claim
28 words
A process as defined in claim 7 wherein the average length of said rods is between 2% and 10% of the average diameter of said shaped catalytic bodies.
Claim 12
Dependent Claim
30 words
A process is defined in claim 7 wherein said rods have an average length:diameter ratio between about 5:1 and 100:1, where the diameter is the maximum diameter of said rods.
Claim 13
Dependent Claim
33 words
A process as defined in claim 7 wherein said catalytic bodies further include from about 0.1 to about 10 weight percent of at least one metal selected from chromium, molybdenum, tungsten and vanadium.
Claim 14
Dependent Claim
32 words
A process as defined in claim 7 wherein said catalytic bodies further include from about 0.1 to about 10 weight percent of at least one metal selected from iron, nickel and cobalt.
Claim 15
Dependent Claim
37 words
A process as defined in claim 1 wherein at least about 60% of the total pore volume in said catalytic bodies is provided by pores with diameters above 200 Angstrom units, as measured by nitrogen desorption isotherm.
Claim 16
Dependent Claim
37 words
A process as defined in claim 7 wherein at least about 60% of the total pore volume in said catalytic bodies is provided by pores with diameters above 200 Angstrom units as measured by nitrogen desorption isotherm.
