Abstract: The present invention provides a method for deep desulfurization of gasoline. The method includes steps of: cutting a gasoline feedstock into light, medium, and heavy gasoline fractions; the medium gasoline fraction being subjected to adsorption desulfurization to obtain a desulfurized medium gasoline fraction; the heavy gasoline fraction being subjected to selective hydrodesulfurization to obtain a desulfurized heavy gasoline fraction; mixing the light gasoline fraction with the desulfurized medium gasoline fraction and the desulfurized heavy gasoline fraction to obtain a desulfurized gasoline, where, a cutting temperature of the light and the medium gasoline fractions is 35-60° C., a cutting temperature of the medium and the heavy gasoline fractions is 70-130° C. The method according to the present invention not only can realize deep desulfurization of gasoline, but also has a less loss of octane number.

Abstract: The present invention provides a process for desulfurizing gasoline fraction by solvent extraction: introducing the gasoline fraction into an extraction tower at a lower-middle part thereof, introducing a solvent into the extraction tower at the top thereof, injecting saturated C5 hydrocarbon into a reflux device at the bottom of the extraction tower, wherein the gasoline fraction which is desulfurized flows out from the top of the extraction tower; the solvent that has extracted sulfide, aromatics and C5 hydrocarbon flows out from the bottom of the extraction tower, and is separated into a C5 hydrocarbon-containing light component, a sulfur-rich component, water and the solvent. The present invention also provides a process for deeply desulfurizing catalytic cracking gasoline, which flexibly combines the process described above and an existing desulfurization technology.
