To　meet　the　technical　requirements　of　reducing　sulfur　and　olefin　contents　in　the　increasingly　stringent　clean　gasoline　standards,　extensive　researches　have　been　carried　out　in　the　field　of　gasoline　cleaning　technology　over　the　world.　In　this　review,　the　recent　progresses　were　summarized　from　the　following　three　aspects:　(1)　the　distributions　of　sulfides　and　olefins　in　fluid　catalytic　cracking　naphtha,　the　octane　numbers　of　different　hydrocarbons,　and　the　hydrogenation　reactivity　of　various　olefins　and　their　suppressing　effects　on　hydrodesulfurization;　(2)　the　advantages　and　disadvantages　of　the　various　fluid　catalytic　naphtha　hydroupgrading　processes,　including　selective　hydrodesulfurization　processes,　the　combined　processes　of　selective　hydrodesulfurization　and　directed　olefin　conversion,　adsorption　desulfurization,　and　the　combined　processes　of　selective　hydrodesulfurization　and　solvent　extraction;　and　(3)　the　typical　models　for　active　metal　sulfides　and　the　recent　advances　in　catalyst　development.　The　aim　of　this　review　is　to　provide　a　brief　but　comprehensive　reference　for　researchers　in　the　field　of　clean　gasoline　production　technology.　©　2019,　Chemical　Industry　Press.　All　right　reserved.
