Combination hydrodesulfurization and reforming process
Abstract
Abstract THE PROCESS COMPRISES CONTACTING A DESULFURIZED NAPHTHA IN A REFORMING ZONE IN THE PRESENCE OF A HYDROGENCONTAINING GAS WITH A REFORMING CATALYST COMPRISING A GROUP VIII NOBLE METAL, A SMALL AMOUNT OF A METAL PROMOTER, AND A COMBINED HALOGEN ON A CATALYTICALLY ACTIVE ALUMINA AT A PRESSURE OF ABOUT 50 P.S.I.G. TO ABOUT 250 P.S.I.G. AND AN INLET TEMPERATURE OF AT LEAST 970* F. TO PROVIDE A REFORMED EFFLUENT CONTAINING INCREASED AMOUNTS OF HYDROGEN AND GASOLINE BOILING COMPONENTS; SEPARATING THE HYROGEN-CONTAINING GAS FROM THE GASOLINE BOILING COMPONENTS AND PASSING THE HYDROGEN-CONTAINING GAS SEQUENTIALLY THROUGH A NAPHTHA-HYDRODESULFURIZATION ZONE, A GASOIL-HYDRODESULFURIZATION ZONE, AND A HEAVY DISTILLATE-HYDRODESULFURIZATION ZONE. THE NAPHTHA BEING HYDRODESULFURIZED IN THE NAPHTHA-HYDRODESULFURIZATION ZONE IS THE DESULFURIZED NAPHTHA THAT IS EMPLOYED IN THE REFORMING ZONE THE PREFERRED METAL PROMOTER OF THE REFORMING CATALYST IS RHENIUM.
