Oxidative desulfurization of fuel oils using ionic liquids: A review

Ultra‐Deep Oxidative Desulfurization of Model Oil Catalyzed by In Situ Carbon‐Supported Vanadium Oxides Using Cumene Hydroperoxide as Oxidant

“…Compared to other methods, ODS has attracted much interest, which is a promising and efficient method for sulfur removal due to its ambient operating conditions . During the ODS process, organic sulfur compounds are oxidized into its corresponding sulfones or sulfoxides, and then the oxidative products can be removed from the oil phase by extraction, adsorption or precipitation with ionic liquids, acetonitrile, activated carbon et al in the following process …”

Formation and Extractive Desulfurization Mechanisms of Aromatic Acid Based Deep Eutectic Solvents: An Experimental and Theoretical Study

“…It is known that sulfur oxidesc auses ignificant environmental and health problems, such as acid rain, respiratory disease, and cancer. [2] Thus,i ti sn ecessary to develop an alternative or supplementary technology with low energyc onsumption and high efficiency of HDS. [2] At present, hydrodesulfurization (HDS), at raditional commercial technology,i sw idely used to purify diesel fuel.…”

“…[1] Thus, as erious of regulations have been established in many countriesf or petroleum refineries to reduce the sulfurc ontento fd iesel fuels to near-zero levels (< 10 ppm), but these regulations have put forth ac ritical challenget ot he refinery industry. Many non-HDS technologiesh ave been developed, such as extractive desulfurization (EDS), [3] oxidative desulfurization (ODS), [2] adsorptive desulfurization (ADS), [4] and others. HDS is ah igh-energy-consumption technology,w hichh as limited capacity to efficiently reduce heterocyclic S-compounds, such as benzothiophene( BT), dibenzothiophene (DBT), and their derivatives.…”

Extractive oxidative desulfurization of model oil/crude oil using KSF montmorillonite-supported 12-tungstophosphoric acid

“…Previous reports have demonstrated the effective catalytic performances of supported HPAs for the oxidation of thiophene (T) and its derivatives with different oxidants (Hui-Peng et al 2007;Kukovecz et al 2002;Yan et al 2009b). However, most of the research up to now has investigated homogenous or amphiphilic catalysts and oxidants (Gao et al 2006;Zhang et al 2012a, b;Maity et al 2009;Qiu et al 2009;Xue et al 2012;Bhutto et al 2016). In these systems, the catalysts are usually dissolved in the continuous phase or inside the emulsion droplets; thus, it is difficult to separate the catalysts and recycle them from the emulsion systems.…”
