“…In view of the strict legislation about fuel quality in many countries, substantial research efforts have been focused on reducing the sulfur concentration of refined petroleum products. To obtain low‐sulfur fuels, hydrodesulfurization (HDS) as the traditional process is often used in the petroleum industry . This technology has been proven to be a robust method in reducing thiol, sulfur mercaptan, sulfide, disulfide, thiophene and derivatives .…”

A new organic-inorganic hybrid nanocomposite (TBA-Si 2 W 18 Mn 4 @SAB) was synthesized by supporting quaternary ammonium salt of sandwich-type polyoxometalate (TBA-Si 2 W 18 Mn 4 ) on sodium-activated bentonite (SAB) for catalysing an oxidative desulfurization (ODS) process. The synthesized materials were characterized by means of elemental analysis, 29 Si NMR, Fourier transform infrared and UV-visible spectroscopies, X-ray diffraction and scanning electron microscopy. The proposed ODS process was successfully developed on the basis of the catalytic oxidation of organosulfur compounds using TBA-Si 2 W 18 Mn 4 @SAB as catalyst and CH 3 COOH/H 2 O 2 as oxidizing agent.The removal of the sulfur content of gasoline reached 97% at a temperature of 35°C after 1 h using 0.10 g of the prepared catalyst. Various experiments were conducted to investigate the effects of reaction time, catalyst amount, reaction temperature and catalyst type on sulfur removal efficiency. The heterogeneous TBA-Si 2 W 18 Mn 4 @SAB catalyst was found to be reusable for five times. The obtained data illustrated that the use of the TBA-Si 2 W 18 Mn 4 @SAB/ CH 3 COOH/H 2 O 2 oxidation system could be a convenient strategy for reducing the sulfur content of gasoline fuel under moderate reaction conditions.

“…Compared to BDS and ADS, EDS could be operated at mild conditions with the use of suitable extractant to desulfurize fuel oil. On the other hand, integrating ODS in EDS system (EODS) will promote the oxidation of sulfur into sulfone components, which can be easily extracted into the solvent phase [15][16][17][18]. Selection of extractant is nonetheless challenging since some of the conventional solvents are highly flammable and volatile [19][20][21].…”

Liquid Polymer Eutectic Mixture for Integrated Extractive-Oxidative Desulfurization of Fuel Oil: An Optimization Study via Response Surface Methodology

et al. 2020

Hydrodesulfurization (HDS) has been commercially employed for the production of ultra-low sulfur fuel oil. However, HDS is unable to remove sterically hindered sulfur-containing compounds such as dibenzothiophene (DBT) and benzothiophene (BT). An alternative way to remove sulfur is via extractive desulfurization system (EDS) using deep eutectic solvents (DES) as sustainable extractant. In this work, liquid polymer DES was synthesized using tetrabutylammonium chloride (TBAC) and poly(ethylene glycol) 400 (PEG) with different molar ratios. Response surface methodology (RSM) was applied to study the effect of independent variables toward extraction efficiency (EE). Three significant operating parameters, temperature (25–70 °C), DES molar ratio (1–3), and DES volume ratio (0.2–2.0), were varied to study the EE of sulfur from model oil. A quadratic model was selected based on the fit summary test, revealing that the extraction efficiency was greatly influenced by the amount of DES used, followed by the extraction temperature and PEG ratio. Although molar ratio of DES was less sensitive towards EDS performance, the EE was much higher at lower PEG ratio. For the realization of an energy-efficient EDS system, optimization of EDS parameters and EE was carried out via a desirability tool. At 25 °C, 1:1 molar ratio of TBAC to PEG, and DES-to-model-oil-volume ratio of 1, removal of DBT reached as high as 79.01%. The present findings could provide valuable insight into the development of practicable EDS technology as a substitute to previous HDS process.

“…Among these new processes, ODS is considered to be one of the promising new methods and is currently receiving growing attention. The greatest advantage of ODS compared with the conventional HDS process is that it can be carried out in the liquid phase, under very mild conditions, and does not need expensive hydrogen [1,10].…”

The article deals with the determination of hydrodynamic parameters necessary to conduct the desulfurization process of straight-run kerosene (SRKF) and straight-run diesel fractions (SRDF) via oxidation of sulfuric organic compounds, followed by the removal of oxidation products. The established parameters which are characterized by the linear rate of the oxidant (air) movement and the dummy contact time between the oxidant and the feedstock allow the process to be carried out without stirring. The proposed technology can be used for the purification of petroleum fuels produced by a small scale, when hydrotreating is economically unprofitable or technologically impossible. This process can also be used for the aftertreatment of hydrogenates and partial desulfurization of straight-run fractions to produce fuel components with improved lubricating properties.
