Process for hydrodesulfurization of catalytic cracked gasoline

摘要

The present invention relates to an effective desulfurization process of catalytically cracked gasoline which reduces olefin content to minimize octane drop. The catalytically cracked gasoline is separated into a plurality of fractions containing one or both of fractions containing a large amount of sulfur compounds which are difficult to desulfurize and fractions containing a large amount of sulfur compounds which are susceptible to desulfurization. One or both of the fractions are hydrodesulfurized. The obtained fraction is mixed with the remaining fraction.
