| 摘 要： | 为了满足清洁能源的要求,采用选择性氧化与相转移催化相结合的方法,在高速均质条件下对催化裂化汽油的脱硫工艺进行了研究。以四丁基溴化铵为相转移催化剂,双氧水为氧化剂,乙酸为助氧化剂,当转速为10 kr/min时反应10 min,汽油的脱硫率可达91%。通过对比脱硫前后的色谱图可知,汽油中大部分含硫化合物被脱除,达到了脱硫的目的。

| Abstract: | To satisfy the need of clean fuels,by combining selective oxidation and phase tranfer catalysis,the desulfurization technology for catalytic cracking gasoline is investigated under high speed homogeneous device.Conclusion is as follow: with tetrabutyl ammonium bromide as the phase transfer agent,hydrogen peroxide as the oxidant,acetic acid as the assist oxidant,the desulfurization rate of FCC gasoline is up to 91% when the reaction time is 10 minutes and the speed of rotation is 10 kr/min.After analyzed by GC-FPD,the most sulfur-containing compounds are obviously reduced,and the purpose of desulfurization is completed. |
