随着人们环保意识的不断增强及原油硫含量的增大,汽车尾气所带来的污染越来越成为人们关注的焦点,生产满足环境保护要求的清洁燃料汽油越来越重要,所以世界各国对燃料油品中的硫含量提出了非常严格的要求。氧化脱硫新技术可以在常温常压,不消耗氢气的条件下使用;另外,还能够有效的脱除传统方法较难脱除的噻吩类硫化物。在反应过程中,V2O5在过氧化氢的氧化作用下产生砜化合物。将相应的砜化物从模拟油和过氧化物中的钒化合物中萃取到离子液内。从两个方向实验了以过氧化氢为氧化剂进行深度氧化脱硫的研究。对模拟油在两种催化剂的催化条件下的不同条件下的反映情况进行分析和总结。
As people’s awareness of environmental protection and crude oil sulfur content increases, the pollution caused by vehicle exhaust more and more become the focus of attention, the production of clean fuel gas to meet the environmental protection requirements more and more important, so all countries in the world Sulfur content in fuel oil sets very strict requirements. Oxidative desulfurization new technology can be used at room temperature and pressure, does not consume hydrogen; In addition, but also can effectively remove the traditional method is difficult to remove thiophene sulfide. During the reaction, V2O5 generates a sulfone compound under the oxidation of hydrogen peroxide. The corresponding sulfone is extracted from the vanadium compound in the simulated oil and peroxide into the ionic liquid. The experiments of deep oxidation desulfurization using hydrogen peroxide as oxidant were carried out in two directions. The simulated oil reaction conditions under different conditions of the two catalysts were analyzed and summarized.
