Abstract

The purpose of the CATALYTIC REFORMING process is the production of high OCTANE NUMBER gasoline which is a strategic and economic in the trade market. In this research, the REGENERATION of commercial Pt-Re/Al2O3 catalyst used for CATALYTIC REFORMING of HEAVY NAPHTHA is studied in the laboratory scale. This catalyst is unloaded from a fixed-bed reactor located in an Iranian refinery, and is at the end of its cycle life (about 2 years). After loading the catalyst in the laboratory scale, for performing the REGENERATION process, the coke on the surface of the catalyst is burned with the dry air. Then, chlorination process is carried out for the redispersion of chlorine agent on the catalyst surface. Finally, the catalyst is reduced and sulfided using hydrogen and H2S streams, respectively. During the REGENERATION, the flow rate, temperature and pressure of process are meticulously controlled, and also the optimized values are chosen to have the best REGENERATION. The results show that the regenerated catalyst, according to the recommended method in this research, has the capability of producing gasoline with the OCTANE NUMBER higher than 100 which is approximately similar to the gasoline produced by the fresh commercial catalyst.
