Web14 Apr 2024 · Extraction oxidation desulfurization (EODS) technology is a new efficient method that combines extraction desulfurization and oxidation desulfurization [11,12]. In the extraction oxidative desulfurization process, the sulfides in the diesel are transferred to the extraction layer, where they are oxidized to sulfones until the diesel is sulfide-free. WebThe oxidation of sulfide can proceed aerobically by two different mechanisms: substrate-level phosphorylation, which is dependent on adenosine monophosphate (AMP), and …
