在H2 O2/醋酸氧化柴油体系中,采用季铵盐型表面活性剂和季铵盐型Gemini表面活性剂作为相转移催化剂(PTC),进行柴油的催化氧化脱硫研究。比较了不同碳链长度的季铵盐型表面活性剂和季铵盐型Gemini表面活性剂的脱硫效果,考察了双子表面活性剂[C12 H25-N+-(C H2)2-N+-C12 H25]·2Br -(C12-2-C12·2Br -)用量、氧化剂用量、反应温度以及反应时间对脱硫效果的影响。结果表明,以C12-2-C12·2Br -作为相转移催化剂,m(PTC)∶ m(柴油)=0.0025,V (氧化体系)∶V(柴油)=0.2,反应温度为70℃,反应时间为1.5 h 时,柴油脱硫率最高可达84.76%,柴油收率为94.52%。
