PMAA microgel surface-supported phase transfer catalyst as reusable microreactors for ultra-deep desulfurization

Oxidative desulfurization of DBT with H2O2catalysed by TiO2/porous glass

“…As a consequence, the overall sulfur removal rate is limited by the mass transfer between phases with active catalysts. Phase transfer catalysts 10,12,[27][28][29][30][31][32][33][34][35][36] have been considered as the potential method to solve this problem. In these phase transfer reaction systems, the amphiphilic catalysts are assembled at the interface between the oil and aqueous phases where sulfur-containing compounds, hydrogen peroxide and catalysts interact with each other.…”
