A series of highly dispersed ionic liquid catalysts were prepared by immobilized acidic ionic liquid [BMIM]HSO4 in silica gel through sol-gel methods. The structures and properties of the catalysts were characterized by FT-IR, SEM and XRD. The results showed the [BMIM]HSO4 had been successfully confined or encapsulated in a silica-gel matrix.

Loading Amount

Mesoporous catalysts [HPMo][HTAC]2/SiO2 with different loading amount of [HPMo][HTAC]2 were prepared by sol–gel method. The catalysts were characterized by XRD, FT-IR, SEM and pore structure parameters. The catalytic activity for the oxidative desulfurization of benzothiophene (BT) and dibenzothiophene (DBT) was evaluated using hydrogen peroxide as an oxidant. Results of the charaterization show that the Keggin structures of all the loaded catalysts were kept and [HPMo][HTAC]2 was highly dispersed on the surface of SiO2. The desulfurization rate of the catalyst 20%[HPMo][HTAC]2/SiO2 can be up to 91% for DBT and 75% for BT in 2 h.

Model Oil

A series of highly dispersed ionic liquid catalysts were used for the oxidation desulfurization of dibenzothiophene (DBT) in model oil in the presence of H2O2. The effects of the loading of [BMIM]HSO4immobilized, reaction time, temperature, O/S molar ratio and the dosage of catalysts on DBT removal were investigated in detail. The catalyst with the loading of [BMIM]HSO4was 25% exhibited the highest activity. The DBT removal of model oil can reach 99.9% in 5 h at 60 °C, O/S molar ratio of 10, Vmodeloil=10mL, mcatalysts=2.00g. The catalysts can be easily recycled and can be recycled 2 times without a significant decrease in activity.
