The present study describes oxidative desulfurization of a model mixture of fluid-catalytic-cracked light cycle oil (LCO). Oxidations of the sulfur compounds have been monitored by FTIR spectroscopy. Oxidized sulfur compounds and degree of desulfurization by oxidation have been determinate by gas chromatography-mass spectroscopy (GC-MS).It has been established that after oxidation and proper extraction process about 90% of the highly refractive by HDS (hydrodesulfurization) sulfur compound like 4,6-Dimethyl-dibenzothiophene (4,6-DMDBT) is removed from the oxidized model mixture.
► A model mixture of fluid-catalytic-cracked light cycle oil (LCO) is studied.
► Oxidative desulfurization of a model mixture of LCO is performed.
► Sulphones were detected by FTIR spectroscopy and GC-MSD analysis.
► The mass spectrum of 4,6-DMDBT sulfone can assess naturally oxidized diesel.
► The oxidation technique is capable of application to cracked diesel feeds like LCO.
