摘要:

随着人们环境保护意识的增强及原油硫含量的增大, 生产满足环境保护要求的清洁燃料是全球炼油工业的发展趋势, 燃料油脱硫显得越来越重要. 在众多的脱硫方法中, 选择性氧化脱硫技术以其工艺条件温和, 脱硫效果明显等特点, 受到了炼油行业的极大关注[1~3], 但脱硫率偏低(30%), 其关键是水相氧化剂与含硫化合物的有效混合. 本文将相转移催化应用于催化裂化(FCC)汽油的氧化脱硫中, 并对脱硫的工艺和机理进行了研究.

Abstract:

AbstractDesulfurization from cracking of gasoline via selective oxidation catalyzed by phase tranfer catalyst is investigated. Using cetyltrimethyl ammonium bromide(CTAB) as the phase transfer catalyst, hydrogen peroxide as the oxidant, acetic anhydride as the assistant oxidant, the effects of different conditions, such as reaction time, reaction temperature, the content of phase transfer catalyst, on the desulfurization rate are investigated. When the volume ratio of gasoline and oxidative system is 0.2, the volume ratio of hydrogen peroxide and acetic anhydride is 5, the content of phase transfer catalysis is 0.06 g, reaction time is 0.5 h, the desulfurization rate of the FCC gasoline is 80.13%. After analyzed by GC-FPD, there is no oxidized sulfur-containing compounds remained in the gasoline.
