Abstract

The oxidative desulfurization of model diesel fuel via H₂O₂-HCOOH by Ultrasonic oxidation and changing stirring speed was studied, and comparing the results of two different ways. The results showed Ultrasonic frequency is 28KHz, ultrasonic power is 800W, water bath and standard atmospheric pressure, V (Diesel) / V (H₂O₂) / V (HCOOH) = 50:1:10, ultrasonic-assisted oxidation for half an hour, the desulfurization rate can reach 98%; after reacting for 1.5h, the desulfurization efficiency can be 98%, when reacting at 40°C, atmospheric pressure and Stirring speed at 1000 rpm. By comparing the results of two methods reacting for 0.5h, ultrasonic desulfurization is better than Stirring speed 1000 rpm in a short time, but in general there is no significant advantage.
