“…Therefore, the development of a sustainable and efficient desulphurization technology is still a hot area of scientific research. There are several ways to remove sulfur from liquid fuels, such as hydrodesulfurization (HDS) [9], biodesulfurization (BDS), extraction desulfurization (EDS), oxidative desulfurization (ODS) [10][11][12], and adsorption desulfurization (ADS) [13,14] (see Figure 2). clean fuel production technology has become one of the key research directions in the petrochemical industry.…”

In recent years, due to the rapid growth of mankind’s demand for energy, harmful gases (SOx) produced by the combustion of sulfur-containing compounds in fuel oil have caused serious problems to the ecological environment and human health. Therefore, in order to solve this hidden danger from the source, countries around the world have created increasingly strict standards for the sulfur content in fuel. Adsorption desulfurization technology has attracted wide attention due to its advantages of energy saving and low operating cost. This paper reviewed the latest research progress on various porous adsorption materials. The future challenges and research directions of adsorption materials to meet the needs of clean fuels are proposed.

“…One of the key problems is the long oxidation time, which significantly complicates the instrumentation of the process. Recently, the issue of reducing oxidation time has received quite a lot of attention. , In particular, catalysts for ultrafast oxidation of sulfur-containing compounds were proposed. Zirconium-containing metal–organic frameworks allow us to achieve complete oxidation of dibenzothiophene (DBT) with hydrogen peroxide in a short time of 5 min In Huang et al, the application of phosphotungstic acid immobilized on the surface of mesoporous titanium oxide was proposed.…”

Simple and highly efficient catalysts obtained by modifying aluminum oxide with sulfuric acid and molybdenum oxide were applied in the process of oxidative desulfurization of model and real diesel fuels. The sequence of modification of the support strongly influences both the chemical composition and acidity of the catalyst. When establishing the correlation between the acidic properties and the content of molybdenum oxide active species, it was shown that the decisive factor influencing the activity of the catalyst is the number of acid sites responsible for the coordination of sulfur-containing substrates. The catalysts were characterized by XRD, nitrogen adsorption−desorption, SEM, TEM, temperature-programmed desorption of ammonia, and X-ray fluorescence. Under optimal conditions of 1.0 wt % of catalyst, a H 2 O 2 /S molar ratio of 4:1, and T = 80 °C, dibenzothiophene was completely oxidized in just 5 min. The 99.9% efficiency of the synthesized S/Mo/Al 2 O 3 catalyst in oxidative desulfurization of the sulfur-rich real diesel fuel (10 100 ppm) in the production of ultralow sulfur diesel was demonstrated in two-step oxidation (5 wt % of catalyst, H 2 O 2 /S molar ratio of 2:1, T = 80 °C).

Defect engineering is often used to improve the performance of catalysts. Here, plasma etching was first used as a strategy to introduce defects to modify the phosphotungstic acid‐based ionic liquids (C14PWIL) catalyst for oxidative desulfurization (ODS) in fuel. The valence band/conduction band value of the catalyst indicates that the formation of oxygen vacancies plays an essential role in enhancing the oxidation capacity. In combination with X‐ray photoelectron spectroscopy results, the enriched electrons in the oxygen vacancies can increase the electron density on the catalyst surface, which promotes the electron migration process between the catalyst and H2O2, thus favoring the activation of H2O2 and enabling an efficient ODS process. The desulfurization efficiency of C14PWIL‐P at room temperature is 3 times that of C14PWIL, which exhibits good cycling stability.
