## Abstract

A process and catalyst is provided for the hydrogenation of a hydrocarbon feedstock comprising a substantial portion of a distillate hydrocarbon feedstock, wherein said distillate hydrocarbon feedstock consists essentially of material boiling between about 150.degree. F. and about 700.degree. F. at atmospheric pressure, which comprises reacting the feedstock with hydrogen at hydrogenation conditions in the presence of a catalyst comprising from about 0.1% to about 2.0% by weight of palladium and from about 0.1% to about 2.0% by weight of platinum and a support comprising borosilicate, for producing a hydrogenated product.

## Claims

### Claim 1

A hydrogenation catalyst suitable for hydrogenation of a hydrocarbon feedstock comprising from about 0.1% to about 2.0% by weight of palladium and from about 0.1% to about 2.0% by weight of platinum, each incorporated onto a support comprising a refractory oxide matrix and borosilicate, wherein said borosilicate, calculated as oxide, comprises from about 30% to about 60% by weight of said support.

### Claim 2 (depends on 1)

The catalyst of claim 1 wherein said support comprises from about 35% by weight to about 45% by weight borosilicate.

### Claim 3 (depends on 1)

The catalyst of claim 1 wherein said borosilicate comprises HAMS- 1B.

### Claim 4 (depends on 1)

The catalyst of claim 1 wherein said refractory oxide matrix comprises an alumina binder.

### Claim 5 (depends on 1)

The catalyst of claim 1 wherein the crush strength of said catalyst is at least 1.3 lb/min.

### Claim 6 (depends on 1)

The catalyst of claim 1 wherein said catalyst comprises from about 0.2% to about 1.5% by weight of platinum and from about 0.2% to about 1.5% by weight of palladium.

### Claim 7 (depends on 1)

The catalyst of claim 1 wherein said catalyst comprises palladium and platinum in a weight ratio ranging from about 5:1 to about 1:5.
