| 摘 要： | 采用溶胶—凝胶法制备改性催化剂Cr-Mo/SiO2.通过红外光谱、X射线衍射、比表面和孔隙分析等方法对Cr-Mo/SiO2进行表征,考察Cr-Mo/SiO2用量、H2O2用量、反应温度和反应时间对模型油和直馏柴油氧化脱硫效果的影响.结果表明,各反应条件对模型油氧化脱硫效果均有一定影响,二苯并噻吩较苯并噻吩更易脱除.直馏柴油氧化脱硫正交试验结果显示,各因素对脱硫率的影响大小排序为:反应温度＞H2O2用量＞Cr-Mo/SiO2用量＞反应时间.最佳反应条件下,可使直馏柴油硫含量由994μg/g降至128μg/g,脱硫率达87.11％,油品回收率不低于98％.

| Abstract: | Cr-modified phosphormolybdic acid supported on silica was prepared by the sol-gel method.The catalyst was characterized by Fourier transform infrared spectroscopy,X-ray diffraction and pore structure parameters,and the influences of catalyst dosage,amount of hydrogen peroxide,reaction temperature and reaction time on the oxidative desulfurization of model oil and diesel fuel were investigated.The results show that all the reaction conditions have certain influence on the oxidative desulfurization,and the ca... |
