## Abstract

A catalyst composition including imogolite and its use in hydrogen processing hydrocarbons are disclosed.

## Claims

### Claim 1

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 (depends on 1)

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 3 (depends on 1)

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 4 (depends on 1)

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 5 (depends on 1)

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 6 (depends on 1)

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 7

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 8 (depends on 7)

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 9 (depends on 7)

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 10 (depends on 7)

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 11 (depends on 7)

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 12 (depends on 7)

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 13 (depends on 1)

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 14 (depends on 7)

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.
