Topic > The desulfurization process to reduce air…

Due to operating conditions such as high temperatures, high pressures and high hydrogen consumption, hydrodesulfurization (HDS) is necessary to achieve ultra-deep desulfurization. High investment and operating costs are inevitable. Therefore, there is a lot of research that has been completed without using hydrogen (not HDS-based) such as adsorption, extraction, oxidation and bioprocessing. The adsorption desulfurization process is usually performed in a fixed bed or fluidized bed. To avoid particle leakage, the particle size of the sorbent is commonly at a larger level, so adsorption desulfurization has a smaller specific surface area and undesirable adsorption efficiency.(Lin et al., 2014)(Gin and Noble, 2011). using a selective solvent to easily react with the sulfur content refers to the extractive desulfurization process.(Horii, Y., 1996). ODS oxidation desulfurization defines the use of different oxidizing agents, such as H2O2 in combination with selective acids such as acetic acid (AcOH), formic acid, NO2.
