    摘要： A method is provided of selecting operating parameters for a reforming process having at least penultimate and final reforming stages, each containing a respective catalyst, for optimum OB/CD production of product reformate having a selected RON and/or over a particular run length. The catalyst lives are determined at constant LHSV for the penultimate and final stage catalysts for a give feed octane to each stage as a function of the change in RON from that of the feed to that of the C.sub.5 + effluent from the respective stage. The penultimate stage C.sub.5 + effluent RON is selected to be such that the lives of the catalysts in each stage are substantially equal. Preferably the yield of C.sub.5 + effluent from each stage and the life of the catalyst used in each stage is determined as a function of the reforming pressure of that stage. The operating pressures of the stages are then selected to be within about 30% of that which gives the highest OB/CD.

    摘要： 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.
