    Abstract: The present invention relates to a method of hydro-upgrading inferior gasoline through ultra-deep desulfurization and octane number recovery. The method comprises the following steps: cutting inferior full-range gasoline into light fraction gasoline and heavy fraction gasolines; contacting the light fraction gasoline successively with a catalyst for selective diene removal and a catalyst for desulfurization and hydrocarbon multi-branched-chain hydroisomerization; contacting the heavy fraction gasoline with the catalyst for selective hydrodesulfurization in a first reactor, and contacting the reaction effluent from the first reactor with a catalyst for supplemental desulfurization and hydrocarbon aromatization/single-branched-chain hydroisomerization in a second reactor; and blending the treated light fraction gasoline and the heavy fraction gasoline to obtain the ultra-clean gasoline product. The hydro-upgrading method of the invention is suitable for hydro-upgrading inferior gasoline, especially for hydro-upgrading inferior FCC gasoline with ultra-high sulfur content and high olefin content to obtain excellent hydro-upgrading effects.
