ABSTRACT:
A process is provided for catalytic reforming or dehydrocyclization of hydrocarbons using a catalyst comprising a noble metal, and an intermediate pore size crystalline silicate having a high silica to alumina ratio and a relatively low alkali content. Preferably, the crystalline silicate is in the form of small crystallite size, such as less than 5 microns. The reforming or dehydrocyclization process is sulfur tolerant so that the reforming can be carried out in the presence of sulfur or with periodic exposure to sulfur.
