摘要
介绍了国内外最新的流化催化裂化 (FCC)汽油的脱硫技术 .包括催化裂化过程中加脱硫剂、选择性加氢脱硫、水蒸汽催化脱硫、生物脱硫、氧化脱硫、吸附脱硫等 .吸附法脱硫具有低投资、低操作成本的优点 .化学吸附具有高硫脱除率的优势 ,可以将汽油中的硫含量降至 10 0 μg/g以下 。
The latest desulfurization technologies of Fluid Catalytic Cracking (FCC) gasoline are introduced.Several processes have been employed for gasoline desulfurization:Selective Hydrogenation Desulfurization,Steam Catalytic Desulfurization.Biode sulfurization,Oxide Desulfurization,Adsorption desulfurization,etc.Adsorption desulfurization have advantages of low investment and low operation cost.Especially Chemical adsorption desulfurization has excellent desulfurization capacity under low pressure,down to the 100 μg/g.Therefore,chemical adsorption will have wide application in improving clean gasoline and environment.
