摘要: 催化氧化脱硫是降低柴油硫含量的非加氢脱硫工艺,在催化氧化溶剂抽提的基础上,增加超声波为反应提供能量。采用H2O2-甲酸作为氧化剂将辽河直馏柴油中的硫化物氧化成相应的砜,考察了氧化反应时间、温度、剂油体积比对脱硫效果的影响。实验结果表明,在超声频率为28 kHz,超声功率为200 W,H2O2和甲酸体积比为1∶1,萃取剂为N,N-二甲基甲酰胺(DMF),一次萃取10 min,萃取剂与油体积比为1∶2的条件下,反应氧化剂与油的体积比为1∶10,温度为50 ℃,氧化反应时间为10 min为较适宜的条件,其脱硫率达到87.8%。

Abstract: Catalytic oxidation is a non-HDS technology to remove sulfur compounds from diesel fuel. On the basis of catalytic oxidation and solvent extraction, ultrasound irradiation was introduced to provide energy for the reaction, which developed a completely new diesel oil oxidative desulfurization technology. The sulfides in Liaohe straight-run diesel fuel had been oxidized to sulfones with H2O2-formic acid as oxidant system was used in the process, the effects of reaction temperature, time and volumic ratio of oxidant and oil were investigated. The results show:under the condition of an ultrasonic frequency of 28 kHz|ultrasonic power of 200 W|the volumic ratio of H2O2 to formic acid 1∶1|extraction solvents N, N-dimethylformamide (DMF)|an extraction time of 10 min and the volumic ratio of extraction solvent to oil is 1∶2, its proper conditions are as follows: volumic ratio of oxidant to oil is 1∶10|reaction temperature is 50 ℃|oxidation time is 10 min|the rate of desulfurization is 87.8%.
