主　　题：Oxidative desulfurization Diesel Ultrasound energy Supported catalyst Low-cost raw materials 

摘      要：An ultrasound-assisted heterogeneous catalytic oxidation process was applied to eliminate sulfur from commercial diesel fuel *** studied variables were catalyst concentration,type of catalyst(homogeneous or heterogeneous),oxidizing agent concentration,and the application of ultrasound *** catalysts were prepared by impregnation of coal fly ash with an iron(Ⅱ)sulfate aqueous solution using ultrasound *** drying,the catalyst was calcined at 500℃for 4 *** oxidizing agent was hydrogen *** energy was applied with a frequency of 47 kHz and an intensity of 147 *** was employed for extracting the oxidized compounds from the hydrocarbon *** fly ash and ethanol were used with the purpose of applying low-cost raw materials in chemical *** was found that under the studied conditions,increasing oxidizing agent concentration and the application of ultrasound energy can enhance the sulfur removal from commercial diesel fuel *** concentration did not play a significant role in the *** results were obtained using homogeneous or heterogeneous catalyst,which is important since the heterogeneous catalyst could be recovered,reactivated,and used in many cycles.
