Hydrogen bonding boosted oxidative desulfurization by ZnCl2/boric acid/polyethylene glycol-based ternary deep eutectic solvents

Breaking new grounds: metal salts based-deep eutectic solvents and their applications- a comprehensive review

“…MS-DESs are a fascinating field of study and advancement in the realm of green solvents due to their versatility and tenability. 12…”

“…Xu and his colleagues 12 reported a series of ternary ZnCl 2 /boric acid/PEG MSDES for the oxidative desulfurization (ODS) of model fuel. Compared with binary DESs, ZnCl 2 /2BA/2PEG displayed 98.7% desulfurization efficiency under optimal conditions (time 3 h, temp 60 °C, oxidant/sulfur ratio 5).…”

“…MS-DESs are a fascinating field of study and advancement in the realm of green solvents due to their versatility and tenability. 12 Researchers are keen to explore novel varieties of MSDESs by tailoring different metal salts with suitable HBA or HBD. However, it must be noted that all metal salts cannot form MSDESs, which limits the variety of MSDESs.…”

Design and Synthesis of Amphiphilic Catalyst [C16mim]5VW12O40Br and Its Application in Deep Desulfurization with Superior Cyclability at Room Temperature

“…Fuel desulfurization has always been an important issue in the fuel refining process because the combustion of sulfur-containing fuel leads to a large amount of SOx emissions, which brings serious environmental problems and even endangers human health. − Hydrodesulfurization (HDS) is a well-established process for the removal of aliphatic sulfides such as mercaptan and thioethers. However, for aromatic sulfides, the use of HDS technology requires higher temperature and pressure, which will inevitably bring out greater security drawbacks and result in higher energy consumption. − In recent years, many non-HDS methods have emerged, such as extraction, adsorption, and oxidative desulfurization (ODS). − Among these developed technologies, ODS has garnered particular attention and is considered a promising complement to HDS due to its high reactivity with aromatic sulfides. − Although H 2 O 2 is a widely used oxidant in ODS, it easily decomposes when heated, which not only reduces the utilization rate but also increases the reaction cost. − Therefore, it is an important research direction with great application value to develop new high-efficiency catalysts for ODS at ambient temperature.…”

Superior stability and activity of a PbMoO4/BiOBr nanocomposite for enhanced catalytic oxidative desulfurization of actual fuel

“…7,8 Catalytic hydrodesulfurization, an industrially anticipated desulfurization process in the domain of the petrochemical industry, can abstract the preponderance of organic sulfur compounds in diesel oil. 9 Catalytic hydrodesulfurization can effectively remove aliphatic sulfur compounds, but for the aromatic ones, conventional catalytic hydrodesulfurization technology is less efficient. 10 Higher pressures and temperatures are preferable to obtain ultra-low sulfur content, which significantly increase operating costs and the release of carbon emissions.…”
