Gasoline Desulfurization Method Comprising Adsorption Desulfurization Of The Light Fraction And Hydrodesulfurization Of The Heavy Fraction

The invention relates to a gasoline desulfurization method consisting of a step in which the gasoline is fractionated into a light fraction comprising thiophenic compounds, such as thiophene or methylthiophenes, and a heavy fraction concentrating the heaviest aromatic sulfur compounds. The heavy fra...

More Information
Summary:The invention relates to a gasoline desulfurization method consisting of a step in which the gasoline is fractionated into a light fraction comprising thiophenic compounds, such as thiophene or methylthiophenes, and a heavy fraction concentrating the heaviest aromatic sulfur compounds. The heavy fraction is treated by hydrodesulfurization, while the light fraction is brought into contact with a solid adsorbent that can be used to eliminate at least part of the light thiophenic compounds, said solid adsorbent being regenerated by a flux within the method.
