摘　　要：文章设计了一种三维大孔磷钨酸/SiO_(2)复合材料。采用红外光谱、扫描电子显微镜和氮气吸附-脱附仪对其结构进行表征,以双氧水为氧化剂,优化条件下模型油中有机硫化物的优化脱硫率可以达到99%以上,采用浓度法计算催化剂氧化反应表观活化能。该技术有望作为加氢脱硫的补充,实现低硫燃油的清洁生产。Three-dimensional ordered macroporous phosphotungstic acid/SiO_(2) composite was prepared and characterized by infrared spectroscopy,scanning electron microscopy and N2 adsorption-desorption isotherm measurement.As-fabricated catalyst exhibits excellent oxidation desulfurization activity in the presence of hydrogen peroxide.99%of organic sulf ide in model oil can be removed under the optimized conditions.Moreover,the apparent activation energy of oxidation reaction was calculated by concentration method.The oxidation desulfurization technology has been regarded as a promising method to hydrodesulfurization to realize the clean production of low-sulfur diesel oil.
