Abstract
ABSTRACTThe phosphomolybdic acid has been successfully supported on functionalized ionic liquid (IL) modified mesoporous silica SBA-15. Subsequently, the obtained products were calcined at different temperatures. The oxidative desulfurization of model fuel containing benzothiophene, dibenzothiophene or 4,6-dimethyldibenzothiophene has been carried out with HPMo-IL/SBA-15 calcined at various temperatures. Based on desulfurization rate and cost, the optimum calcination temperature of HPMo-IL/SBA-15 catalyst was around 400 °C. More molybdenum oxide active sites were shown by the decomposition of the IL at the higher temperature, which caused better desulfurization performance.
摘要在功能化离子液体(IL)修饰的介孔二氧化硅SBA-15上成功负载了磷钼酸。随后,将所得产物在不同温度下进行煅烧。用hmo - il /SBA-15在不同温度下煅烧,对含苯并噻吩、二苯并噻吩或4,6-二甲基二苯并噻吩的模型燃料进行了氧化脱硫。基于脱硫速率和成本考虑,hmo - il /SBA-15催化剂的最佳焙烧温度为400℃左右。在较高的温度下,氧化钼的活性位点较多,脱硫性能较好。
