摘要
Desulfurization 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.
Desulfurization from cracking of gasoline v/a 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.
