The catalytic naphtha reforming process: hydrodesulfurization, catalysts and zeoforming

  • Walid Nabgan

High-octane gasoline production by catalytic naphtha reforming is a major process in the petroleum industry. Sulfur components involved in the reforming process are causing pollutions and catalyst poisoning. Hydrodesulfurization has been developed to remove sulfur species from naphtha. Bimetallic and trimetallic catalysts are used to improve the naphtha reforming. Another solution to produce gasoline is the zeoforming process, which involves zeolites. This article reviews the naphta reforming reaction.
