Effects of nitrogen compounds, aromatics, and aprotic solvents on the oxidative desulfurization (ODS) of light cycle oil over Ti-SBA-15 catalyst

- Ti-SBA-15 catalyst was active for the ODS of LCO feed.
- Nitrogen compounds strongly inhibit the ODS of refractory sulfur compounds.
- Aromatics and aprotic solvent promoted LCO ODS via dissolving oxidized products.
