| description | Relating to the field of hydrocarbon oil refining, the invention discloses a method for reducing the gasoline sulfur content. The method includes: fractionating a gasoline raw material into light fraction gasoline, medium fraction gasoline and heavy fraction gasoline, letting the light fraction gasoline firstly enter an alkaline extraction unit for removal of mercaptan, then mixing the mercaptan removed light fraction gasoline with medium gasoline fraction, and letting the mixture enter a solvent extraction unit; or letting the medium gasoline fraction firstly enter the solvent extraction unit, then mixing the obtained product and the light gasoline fraction, and subjecting the mixture to the alkaline extraction unit; letting the extract oil obtained by the solvent extraction unit and theheavy fraction gasoline enter a first reaction zone and a second reaction zone in order, and separating the reaction effluent of the second reaction zone to obtain hydrogenated heavy fraction gasoline; and mixing the treated |
