Abstract: THE DISCLOSURE IS DIRECTED TO SYSTEMS FOR THE CATALYTIC REFORMING OF GASOLINE BOILING RANGE HYDROCARBONS TO IMPROVE THEIR OCTANE RATING. REFORMING IS CONDUCTED IN THE PRESENCE OF MOLECULAR HYDROGEN AND PLATINUM GROUP METAL-TYPE CATALYSTS DISPOSED IN A PLURALITY OF FIXED BED REACTION ZONES. IN AN INITIAL DEHYDROGENATION REACTION ZONE THE CATALYST CONTAINS A PLATINUM GROUP METAL AND RHENIUM ON AN ALUMINA SUPPORT WHILE IN A SUBSEQUENT PARAFFIN DEHYDROCYCLIZATION PART OF THE SYSTEM THE CATALYST CONTAINS A PLATINUM GROUP METAL ON ALUMINA. IN A SPECIAL OPERATION THE INLET TEMPERATURES OF THE REACTORS CAN BE CONTROLLED WITH RESPECT TO THE LENGTH OF THE TOTAL REFORMING CYCLE.

Abstract: The disclosure is directed to systems for the catalytic reforming of gasoline boiling range hydrocarbons to improve their octane rating. Reforming is conducted in the presence of molecular hydrogen and platinum group metal-type catalysts disposed in a plurality of fixed bed reaction zones. In an initial dehydrogenation reaction zone, the catalyst contains a platinum group metal and rhenium on a solid, acidic oxide type support while in a subsequent, paraffin dehydrocyclization part of the system, the platinum group metal is disposed on a base of relatively low acidity, e.g., alumina. In a special operation, the inlet temperatures of the reactors can be controlled with respect to the length of the total reforming cycle.
