## Abstract

This invention relates to a method of reforming gasoline to raise the octane number thereof utilizing a novel catalyst comprising a low valence titanium, vanadium and/or chromium metallic component composited with a non-oxidizing high surface area support. The low valence metallic component is present in divalent form or as a combination of the metallic state and the divalent form-- preferably as a chloride and/or bromide. The preferred support is a high surface area coke.

## Claims

### Claim 1

In a method of reforming a gasoline feed in the presence of a reforming catalyst to raise the octane number thereof, the improvement which comprises utilizing a reforming catalyst comprising:
(a) a catalytic component selected from the group consisting of titanium, vanadium and mixtures thereof, said catalytic component being present in divalent form or in an admixture of the divalent form and the metal, the ratio of the catalytic component in divalent form to the catalytic component present as the metal being at least 1:1; and
(b) a high surface area support for said catalytic component which will not oxidize said catalytic component at reforming conditions to a valence state higher than the divalent valence state.

### Claim 2 (depends on 1)

The method of claim 1 further characterized in that the catalytic component is present in the form of a chloride, bromide or a mixture of chlorides and bromides.

### Claim 3 (depends on 2)

The method of claim 2 further characterized in that the catalytic component comprises vanadium.

### Claim 4 (depends on 2)

The method of claim 2 further characterized in that the catalytic component comprises titanium.

### Claim 5 (depends on 1, 2, 3, 4)

The method of claims 1, 2, 3 or 4 further characterized in that the high surface area support comprises coke having a surface area of from about 200 to about 500 M.sup.2 /g.

### Claim 6 (depends on 5)

The method of claim 5 further characterized in that the catalytic component of the reforming catalyst is present in an amount of from about 5% to about 10% by weight based on the weight ratio of metal in the catalytic component to high surface area support.
