| 摘 要： | 在H2O2/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[C12H25-N+-(CH2)2-N+-C12H25]·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)=0.002 5,V(氧化体系)∶V(柴油)=0.2,反应温度为70℃,反应时间为1.5h时,柴油脱硫率最高可达84.76%,柴油收率为94.52%。

| Abstract: | Catalytic oxidation desulfurization of diesel in the H2O2/acetate oxidative diesel des-ulfurization system by quaternary ammonium surfactants and quaternary ammonium Gemini sur-factants as phase transfer catalyst （PTC） was studied .The desulfurization effect of quaternary ammonium surfactants and quaternary ammonium Gemini surfactants with different carbon chain was compared .Furthermore ,the effects of [C12H25-N＋-（CH2）2-N＋-C12H25]· 2Br-dosage ,oxi-dant dosage ,reaction temperature and reaction time on the desulfurization performance were in-vestigated .The result showed that the desulfurization rate of diesel fuel could be up to 84 .76%and the diesel yield reached 94 .52% while the mass ratio of PTC and diesel fuel was 0.002 5 and volume ratio of oxidation system and diesel fuel was 0.2 after 1.5h in reaction at 70 ℃ ,taking [C12H25-N＋-（CH2）2-N＋-C12H25] · 2Br-as the phase transfer catalyst . |
