ABSTRACT:
Catalytic cracking or steam cracking effluents are desulfurized without substantial decrease of their octane number by subdividing said effluent into two fractions of different boiling ranges, the heavier of which is admixed with hydrogen, the resulting mixture being completely vaporized and fed to a hydrodesulfurization zone containing a first bed of selective catalyst formed of cobalt and molybdenum, or cobalt and tungsten, or nickel and molybdenum or nickel and tungsten deposited on a non-acid carrier, and a second bed of conventional hydrodesulfurization catalyst, the effluent from the hydrodesulfurization zone being cooled down and fractionated to separate a hydrocarbon fraction of the gasoline range which is recombined with the lighter fraction of said effluent.
