“…4,6-DMDBT > 4-MDBT > DBT > BT. This was in good agreement with the results of Aida et al [27][28][29] who also performed the oxidation of DBT with hydrogen peroxide and formic acid. Thus, it suggests that the oxidation reactivity is enhanced for sulfur atoms with a high electron density.…”

“…Moreover, the commonly used process are either expensive or less effective at achieving these levels. [27][28][29] Oxidants such as hydrogen peroxide (H 2 O 2 ) and organic carboxylic acids are commonly used in the ODS process. Among these new methods, oxidative desulfurization (ODS) is considered to be one of the most promising methods for the deep desulfurization of fuel oil.…”

In the present work, hybrid magnetic nanoparticles based on Fe and FeMo coated with carbon nanostructures (Fe/C and FeMo/C) were produced by catalytic chemical vapor deposition at different temperatures using ethanol as the carbon source. Scanning electron microscopy, thermal analysis, Raman spectroscopy, X-ray diffraction, and Mössbauer spectroscopy analyses suggested that hematite was reduced by ethanol at 700 and 900 1C, producing carbon nanostructures such as nanofibers and nanotubes. The Fe/C and FeMo/C hybrid composites showed remarkable magnetic and amphiphilic properties. The composites were successfully used to oxidize sulfur and nitrogen contaminants present in fuels in a biphasic system.

“…2 Large efforts have been made in the field of hydrodesulfurization to overcome their very low reactivity by the development of new catalysts, 3 or new processes. 4 Moreover new approaches such as biocatalytic desulfurization, 5 adsorption processes 6 or oxidation of sulfur compounds 7 have shown interesting results. Nevertheless none of these methods has offered up to now an economically satisfactory answer for the removal of the refractory alkyldibenzothiophenes from gasoils.…”

A new method has been recently developed for the hydrodesulfurization of gasoils based on the formation of charge transfer complexes. This method is highly selective towards the removal of alkyldibenzothiophenes from other aromatic compounds present in gasoils. Total energy calculations based on density-functional theory have been performed to study the complexation phenomenon and clarify its high selectivity. DFT calculations improve the understanding of the process and they are also useful for the design of more efficient acceptor derivatives for the desulfurization process. Five charge transfer complexes between a given acceptor and five representative donor compounds present in gasoils have been studied. Three main criteria have been used to characterize the optimized complexes: their complexation energy, their geometry and their electronic structure. The decomposition of total energy showed that the main contribution to the complexation energy comes from the Pauli repulsion and the electrostatic interactions. Hence the charge transfer complexes are not only ruled by charge transfer but also by electrostatic contributions. However, the selectivity of the complexation phenomenon is controlled by the orbital interactions.
