摘要

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.
