Research progress in H2O2/solid catalyst carrier for oxidative desulfurization

The article summarizes the research progress and development of carriers in the system of oxidative desulfurization with solid catalyst H₂O₂. Advantages, disadvantages and application results are discussed from following four aspects:single oxide carrier, mixed oxide carrier, activated carbon carrier, molecular sieve and composite molecular sieve carrier. As single carriers, Al₂O₃, TiO₂, SiO₂ and ZrO₂ are emphatically introduced; and binary compound oxides are specially introduced in mixed oxide carriers. The molecular sieve and composite molecular sieve carrier represented by ZSM-5, SBA-15, MCM-41 and HMS are also introduced emphatically. Finally, we give an induction and summarization on structural characteristics, advantages and disadvantages in the reaction of different carriers. The research tendency of oxidative desulfurization carrier is prospected, meanwhile, molecular sieve and composite molecular sieve carrier are proposed as the key research focuses of catalyst carriers for oxidative desulfurization in the future.
