Deep desulfurization of model oil using green amino acid ionic liquids combined with H₂O₂

Amino Acid Ionic Liquids Supported on Nano‐Sized MnO2 for Deep Desulfurization of Model Fuels

“…According to the results of the desulfurization experiment with [C n min]Br (see Sect. 4.2.1), [C 8 min]Br was preferably used to synthesize amino acid IL, which is consistent with the results in the literature 10.…”

“…The preparation procedures for the amino acid IL are described in a previously published article 10. [C n min]Br ( n = 4, 6, 8, 12) were first synthesized.…”

“…The application of ionic liquids (IL) in engineering has become a hot research topic due to the obvious advantages of IL, such as the low saturated vapor pressure, high thermal stability, designable structure, good reusability, no pollution to the environment, and no corrosiveness 10, 16, 17. In the past two decades, many researchers have paid attention to desulfurization by IL, and many articles have been published.…”

“…Therefore, ODS is considered by the majority of researchers to have great application prospects [6][7][8][9]. However, the addition of an oxidant (e.g., H 2 O 2 ) in the ODS process will cause side reactions, which will lead to the decline of the fuel quality, and the cost will be high due to the use of a large number of oxidants [10]. When polyoxometalate-based catalysts were used in the ODS process, the above disadvantages of ODS were greatly improved [11][12][13][14][15].…”

Synthesis of modified amphiphilic quaternary ammonium silicotungstate and its application in heterogeneous catalytic oxidative desulfurization

“…In order to achieve deep desulfurization, many materials like ionic liquids, 17,18 heteropoly acids (HPA), 19,20 deep eutectic solvents 21,22 and organic metal frameworks (MOFs) 23,24 have been researched. HPA, a kind of transition metal oxacid, has the advantages of high catalytic activity, great heat stability, comprehensive solubility and environmental protection.…”
