Desulfurization Methods of Liquid Fuels

In this research, desulfurization methods of liquid fuels such as Hydrodesulfurization, Oxidative desulfurization, Biodesulfurization, Absorption desulfurization, Extraction desulfurization and Supercritical water desulfurization are studied. Strengths and weaknesses, parameters and challenges facing each of the methods are investigated. Among these methods, hydrodesulfurization, oxidation desulfurization and absorption desulfurization have industrial technology. But biodesulfurization, extraction desulfurization and supercritical water desulfurization have not Industrial technology and studies continue in this field. Despite these progresses still the most common industrial technology for the sulfur removal is hydrodesulfurization, although this method has disadvantages. Researchers in the fields of oil refining, trying to improve and enhance the current desulfurization methods and find new desulfurization methods for achievement to industrial tchnology of clean fossil fuels production.
