The invention belongs to the field of hydrocarbons refining, and discloses a gasoline deep desulfurization method and equipment used for gasoline deep desulfurization. The gasoline deep desulfurization method comprises following steps: 1, gasoline raw material is subjected to fractionation so as to obtain light fractions and heavy fractions; 2, the light fractions are subjected to pre-hydrogenation so as to obtain pre-hydrogenated light fractions; 3, the pre-hydrogenated fractions are subjected to solvent extraction so as to obtain a sulfur-containing solvent and solvent-extracted light fractions, distillation is adopted to separate the sulfur-containing solvent from sulfides contained by the sulfur-containing solvent so as to obtain a solvent extracted sulfur-containing material and a recycled sulfide-free solvent; 4, the heavy fractions are subjected to selective hydrodesulfurization reaction so as to obtain hydrogenated heavy fractions; and 5, the hydrogenated heavy fractions and the solvent-extracted light fractions are mixed so as to obtain gasoline products. The gasoline deep desulfurization method is capable of obtaining gasoline products lower in sulfur content without large reduction of octane value.
