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.
