Novel Methods for Desulfurization of Fuel Oils
Because of the requirement for low sulfur content of fuel oils, it is necessary to develop alternative methods for desulfurization of heavy fuel oil. Due to the disadvantages of HDS technologies such as costs, safety and green environment, new methods have been developed. Among these methods is ultrasoundassisted oxidative desulfurization. Using ultrasound-assisted oxidative desulfurization, co...
متن کاملAdvances in Desulfurization Research of Liquid Fuel
The new requirements for sulfur content in liquid fuels demand the use of novel deep desulfurization processes. 4-methyldibenzothiophene, 4,6dimethyldibenzothiophene and their alkyl-substituted derivatives are the key substances that need to be separated from diesel fuel and fuel oil. These compounds require higher hydrogen consumption in the hydrodesulfurization process and the use of addition...
متن کاملRole of phosphorus in carbon matrix in desulfurization of diesel fuel using adsorption process
Adsorptive removal of dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (DMDBT) from model diesel fuel with 20 ppmw total concentration of sulfur was investigated on polymerderived carbons with incorporated heteroatoms of oxygen, sulfur and phosphorus. The materials before and after exposure to model diesel fuel were characterized using adsorption of nitrogen, thermal analysis, potentiome...
متن کاملOxidative desulfurization of light fuel oil by using hydrogen peroxide in the presence of acetic acid catalyst
Hydrogen peroxide as an oxidant agent was used for desulfurization of a petroleum hydrocarbon fraction (C10-C22) with boiling range of 175-375 ℃, (light fuel oil) in the presence of acetic acid as catalyst. The oxidation was performed in an ultrasonic bath. It is found that increasing the amount of hydrogen peroxide lead to increase the oxidation rate and so desulfurizatio...
متن کاملOxidative desulfurization of fuel oil by pyridinium-based ionic liquids.
In this work, an N-butyl-pyridinium-based ionic liquid [BPy]BF(4) was prepared. The effect of extraction desulfurization on model oil with thiophene and dibenzothiophene (DBT) was investigated. Ionic liquids and hydrogen peroxide (30%) were tested in extraction-oxidation desulfurization of model oil. The results show that the ionic liquid [BPy]BF(4) has a better desulfurization effect. The best...
