Abstract
Porous aromatic frameworks modified by sulfonic groups were synthesized and, for the first time, applied for the oxidative desulfurization of a model and a real fuel. The main factors affecting the process including the catalyst dosage, temperature, reaction time, oxidant dosage, and hydrogen peroxide concentration were investigated in detail. Under optimal conditions, dibenzothiophene (DBT) was removed completely. It was shown that the synthesized catalysts reduced the sulfur content in the straight-run gasoline fraction up to ultra-low values (7 ppm). Fuel fractions and their oxidation products were analyzed by two-dimensional gas chromatography with time-of-flight mass spectrometry detection. No byproducts of hydrocarbon oxidation were found, which confirms the high selectivity of oxidation in the presence of synthesized catalysts. These catalysts retain their activity in DBT oxidation for at least five cycles.
