ИСТИНА

The method for the synthesis of SILP heterogeneous catalysts based on sulfated IL (4-(3’-ethylimidazolium)-butanesulfonate) protonated by Mo- and W-based heteropolyacids was proposed. SILP catalysts on SiO2 decrease residual sulfur content of less than 10 ppm in diesel fuel, that meets modern environmental requirements. So, the obtained catalysts combine high catalytic activity and stability in the desulfurization of sulfur-containing components of petroleum raw materials with perfect synthetic availability.
