Methods for producing supported catalysts containing a transition metal and a bound zeolite base are disclosed. These methods employ a step of impregnating the bound zeolite base with the transition metal, fluorine, and high loadings of chlorine. The resultant high chlorine content supported catalysts have improved catalyst activity in aromatization reactions.

The present disclosure relates to a reforming catalyst composition comprising a spherical gamma AI.sub.2O.sub.3 support; at least one Group VB metal oxide sheet coated on to the AI.sub.2O.sub.3 support; and at least one active metal and at least one promoter metal impregnated on the AI.sub.2O.sub.3 coated support. The reforming catalyst composition of the present disclosure has improved activity, better selectivity for total aromatics during naphtha reforming and results in less coke formation. The reforming catalyst composition has improved catalyst performance with simultaneous modification of acidic sites as well as metallic sites through metal support interaction. The acid site cracking activity of the catalyst is inhibited because of the use of chloride free alumina support modified with solid acid such as Group VB metal oxide and impregnated with active metals. The present disclosure provides a process for naphtha reforming in the presence of the reforming catalyst composition of the present disclosure to obtain reformates of naphtha.
