“…Mesoporous silicas, such as MCM-41, SBA-15, and others, are frequently used as the catalyst carriers. − Mesoporous materials have the following features: high specific surface area (up to 1000 m 2 /g) and narrow size distribution of wide pores (∼4 nm), wherein a steric hindrance for adsorption of bulky sulfur-containing molecules (for example, alkyldibenzothiophenes) is absent. , In general, the ODS catalysts are polyoxometallates or oxides of molybdenum and tungsten supported on MCM-41, , but titanium, iron, and nickel are used scarcely. , Using these catalysts, model sulfides are oxidized completely. , …”

Mesoporous silicas of MCM-41 type modified by transition metal oxides, such as molybdenum, vanadium, and tungsten, were synthesized. These materials were characterized by low-temperature nitrogen adsorption/desorption, Fourier transform infrared spectroscopy, X-ray spectral fluorescence analysis, and transmission electron microscopy techniques and applied for the removal of sulfur compounds in model and real fuels by oxidative desulfurization. The catalysts obtained were tested under optimal conditions. Dibenzothiophene was removed completely, and sulfur removal in gasoline and diesel fractions could reach 91 and 63%, respectively. These catalysts retain their activity in gasoline fraction desulfurization for 5 cycles.
