通过研究高烯烃含量FCC汽油的烃类组成和结构，针对性地开发了具有深度脱硫和烯烃饱和能力并减少辛烷值损失的RIDOS技术。RIDOS技术的多种功能是通过一系列新催化剂实现的，具有良好的原料适应性和操作稳定性。第一套RIDOS技术工业应用结果表明产品中硫的质量分数可小于10 μg/g，烯烃体积分数小于20％，抗爆指数损失仅1.3。RIDOS技术为生产满足更苛刻标准的汽油提供了可能。

By analysis of the component and structure of real high olefinic FCC naphtha, a technology of deep desulfurization and olefin saturation with minimal octane loss is developed, which is named RIDOS. The multifunctions of RIDOS technology are achieved by using a series of new catalysts, which show the good feed adaptability and operation flexibility. The results of the first commercial RIDOS unit show that an ultra-low sulfur (w(S)＜ 10 /μg/g), low olefins gasoline (φo＜20%) is produced, while the road octane number loses only 1.3 unit. RIDOS technology provides the possibility for producing the clean fuels meeting most strict specifications.
