Oxidative desulfurization of diesel with TBHP/isobutyl aldehyde/air oxidation system

One-pot extraction combined with metal-free photochemical aerobic oxidative desulfurization in deep eutectic solvent

“…[9][10][11] Compared with other non-HDS methods, such as adsorption desulfurization (ADS), [12][13][14] extraction desulfurization (EDS) [15][16][17] and biodesulfurization, 18 oxidative desulfurization (ODS) is one of the most promising methods due to its moderate reaction environment, high desulfurization and its ability to preserve the octane number compared to HDS. 5,[19][20][21] Many classical oxidants including oxygen, [21][22][23][24] hydrogen peroxide, [25][26][27][28][29] ozone 30,31 and organic hydroperoxide 32 have been reported, among which molecular oxygen (O 2 ) is the most green and low-cost oxidant. However, its triplet ground state makes it inactive in many redox reactions.…”

Oxidative desulfurization of dibenzothiophene catalyzed by α-MnO2 nanosheets on palygorskite using hydrogen peroxide as oxidant

“…Aer the reaction, the catalyst was centrifuged and the upper layer of the reaction samples withdrawn and subjected to gas chromatography-pulsed amephotometric detection. 24 Results and discussion XRD of samples XRD was used to characterize the phase and crystal structure of the samples. 26,27 TGA Fig.…”

Photocatalytic oxidative desulfurization of dibenzothiophene by C/TiO2@MCM-41 nanoparticles under visible light and mild conditions

“…This is not only for legislation enforcing environmentally friendly transportation fuel but also the severe requirement of liquid hydrocarbon fuels with sulfur content of less than 1 ppmw for fuel cell applications. [6][7][8][9][10] Photocatalysis has emerged as a promising technology for the degradation of organic pollutants. Although HDS process is a conventional technology for desulfurization of liquid fuels, it cannot efficiently eliminate refractory compounds such as alkylthiophenes, benzothiophene (BT), dibenzothiophene (DBT), and its derivatives.…”

“…The photocatalytic ODS is attracting interest, because of its low cost and mild operation of conditions. [6][7][8][9][10] Photocatalysis has emerged as a promising technology for the degradation of organic pollutants. TiO 2 is the most widely used photocatalyst in various applications due to its high photocatalytic activity, lower cost, nontoxic nature, chemical inertness, and simplicity but it has some disadvantages.…”
