Abstract
A process for reforming a hydrocarbon which comprises treating the hydrocarbon, while at elevated temperature, with a transition metal catalyst while in the presence of an effective amount of gaseous oxygen to improve the selectivity of the catalyst to aromatic formation and reduce the hydrogenolysis activity of the catalyst. The transition metal may be tungsten, and the transition metal catalyst may be supported on an oxidic support, optionally with a ceramic passivation layer lying between the support and the transition metal catalyst. The amount of gaseous oxygen used may be from about 50 ppm to about 5000 ppm, based upon the weight of the hydrocarbon.
