More particularly, the invention is directed to the catalytic reforming of hydrocarbons. Even more specifically, the present invention is directed to a catalyst composition useful for the catalytic reforming of naphtha feedstocks. Catalytic reforming is the most important hydrocarbon conversion process employed in the petroleum industry. It is a process for converting naphtha fractions to high octane gasoline. The process is particularly important for the production of high quality gasoline since it increases the content of aromatics. These aromatics enhance the octane number of the gasoline by contributing to the formation of a more stable and highly aromatic ortho-para isomer. The other major products of catalytic reforming are light naphtha, normally composed of C.sub.5 -C.sub.10 hydrocarbons, and dehydrogenated hydrocarbons containing mostly C.sub.6 -C.sub.10 hydrocarbons. The catalytic reforming process is accomplished by contacting hydrocarbon feedstock, e.g., naphtha fractions, with a catalyst composition comprising a metal hydrogenation-dehydrogenation (hydrogen transfer) component, e.g., platinum, and an acidic support component, e.g., halogen-treated aluminosilicate, under reforming conditions, i.e., temperatures in the range of 400.degree.-600.degree. F., pressures in the range of 50-3000 psig, and liquid hourly space velocities (LHSV) of 0.1-10. A typical catalyst composition may contain about 3 wt. % of platinum and about 1 wt. % of halogen. The catalytic reforming reaction is a dehydrogenation process. The most significant reaction taking place during reforming is the dehydrogenation of cyclohexanes to aromatics. Other reactions taking place include dehydroisomerization, dehydrocyclization, and the dealkylation of alkylbenzenes. The overall dehydrogenation reactions which take place during reforming are: ##STR1## The dehydrogenation reactions are essentially be359ba680
