    • A process for desulfurizing catalytically cracked gasoline containing sulfur compounds and olefin components, which comprises the steps of:1) first desulfurizing the catalytically cracked gasoline in the presence of a hydrodesulfurization catalyst at a desulfurization rate of 60 to 90%, a reaction temperature of 200 to 350.degree. C., a hydrogen partial pressure of 5 to 30 kg/cm.sup.2, a hydrogen/oil ratio of 500 to 3,000 scf/bbl, and a liquid hourly space velocity of 2 to 10 1/hr, said first desulfuriing step comprising supplying a feed having a hydrogen sulfide vapor concentration of not more than 0.1% by volume, and2) next desulfurizing the treated oil obtained in the first step in the presence of a hydrodesulfurization catalyst at a desulfurization rate of 60 to 90%, a reaction temperature of 200 to 300.degree. C., a hydrogen partial pressure of 5 to 15 kg/cm.sup.2, a hydrogen/oil ratio of 1,000 to 3,000 scf/bbl, and a liquid hourly space velocity of 2 to 10 1/hr, said second desulfurizing step comprising supplying a feed having a hydrogen sulfide vapor concentration of not more than 0.05% by volume. A reduction in octane number due to hydrogenation of olefin components is minimized while achieving a high desulfurization rate.
