Abstract
Describes
oxidative desulfurization of a model mixture of fluid-catalytic-cracked light
cycle oil (LCO). Oxidations of the sulfur compounds were monitored by FTIR
spectroscopy. Oxidized sulfur compounds and degree of desulfurization by
oxidation were determinad by gas chromatography-mass spectroscopy (GC-MS).
Researchers determined 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.
