## Abstract

A three-component catalyst is prepared comprising a particulate silica adsorbent with boron trifluoride and water adsorbed on the silica. The silica-water-boron trifluoride catalyst is used in hydrocarbon conversion reactions such as the oligomerization of 1-decene to a product predominating in the trimer and tetramer.

## Claims

### Claim 1

A three-component hydrocarbon conversion catalyst comprising particulate silica having boron trifluoride and water adsorbed thereon, said catalyst obtainable by the adsorption on said particulate silica of water and boron trifluoride from a liquid hydrocarbon in the presence of an atmosphere comprising boron trifluoride.

### Claim 2 (depends on 1)

A three-component catalyst in accordance with claim 1 in which the silica has a particle size of between about 3 and about 400 mesh.

### Claim 3 (depends on 2)

A three-component catalyst in accordance with claim 2 in which the partial pressure of boron trifluoride in said atmosphere is between about atmospheric pressure and about 1,000 psig.

### Claim 4 (depends on 3)

A three-component catalyst in accordance with claim 3 in which the water is present in the liquid hydrocarbon in an amount of between about 5 and about 130 ppm.

### Claim 5 (depends on 1)

A three-component catalyst in accordance with claim 1 in which the silica has a particle size of between about 10 and about 50 mesh.

### Claim 6 (depends on 2)

A three-component catalyst in accordance with claim 2 in which the partial pressure of boron trifluoride in said atmosphere is between about 10 and about 250 psig.

### Claim 7 (depends on 6)

A three-component catalyst in accordance with claim 6 in which the water is present in the liquid hydrocarbon in an amount of between about 20 and about 100 ppm.
