Oxidative desulfurization of fuel oil by pyridinium-based ionic liquids.
In this work, an N-butyl-pyridinium-based ionic liquid [BPy]BF(4) was prepared. The effect of extraction desulfurization on model oil with thiophene and dibenzothiophene (DBT) was investigated. Ionic liquids and hydrogen peroxide (30%) were tested in extraction-oxidation desulfurization of model oil. The results show that the ionic liquid [BPy]BF(4) has a better desulfurization effect. The best...

Inexpensive and low-viscosity Protic Acidic Ionic Liquids (PAILs) of N-metheyl-2-pyrrolidone formate, acetate, and propionate abbreviated as [Hnmp][HCOO], [Hnmp][CH3COO] and [Hnmp][CH3CH2COO] respectively, were prepared and characterized by FT-IR and H-NMR. Deep oxidative and extractive desulfurization of a simulated oil and a real diesel containing 1000 ppm...
متن کاملRecent Advances in the Science and Technology of Desulfurization of Diesel Fuel Using Ionic Liquids
Sulfur-containing compounds in transportation fuels are converted by combustion to SOx, which is a major source of acid rain and air pollution [1]. For environmental protection pur‐ poses, many countries have mandated a reduction in fuels sulfur level down to 10 ppm by 2009 [2,3], and with more and more stringent regulatory constraints, it is a trend to achieve little-to-no sulfur fuels in the ...
متن کاملDeep Extractive Oxidative Desulfurization of Model Oil by Magnetically Recoverable Polyoxometalate-Based Nano Catalyst
Dibenzothiophene (DBT), benzothiophene (BT) and thiophene (T) were catalytically oxidized to their corresponding sulfone products by H2O2 in the presence of magnetically recoverable polyoxometalate-based nano catalyst. Different extracting solvents including ethanol, acetonitrile, and dimethylformamide were tested. The best results were obtained by ethanol extraction. The oxidative desulfurizat...
متن کاملOxidative desulfurization of dibenzothiophene with molecular oxygen using emulsion catalysis.
Dibenzothiophene (DBT) is oxidized to the corresponding sulfoxide and sulfone in an emulsion system (W/O) composed of polyoxometalate anion [C(18)H(37)N(CH(3))3](5)[PV(2)Mo(10)O(40)] as both the surfactant and catalyst, using molecular oxygen as the oxidant and aldehyde as the sacrificial agent under mild conditions.
