Oxidative desulfurization of synthetic diesel using supported catalysts

Deep oxidative desulfurization of liquid fuels

“…Vanadium-based catalysts have also been used for CODS (Schultz et al 1963, Gomez and Cedeño 2003, Shiraishi et al 2003, Cedeño et al 2005, Cedeño Caero et al 2006, Cedeño-Caero et al 2008, Gonzalez-Garcıa and Cedeno-Caero 2009. The result of a CODS study showed a %SC of DBT and 4,6-DMDBT as high as 99.9% and 82.2%, respectively, at 60°C using V 2 O 5 /TiO 2 catalyst and H 2 O 2 as oxidant.…”

Deep extractive desulfurization of oil over 12-molibdophosphoric acid encapsulated in metal-organic frameworks

“…In ODS catalysis, only a few papers have investigated the influence of nitrogen-containing compounds [16][17][18][19]. Cedeño et al found that quinoline, indole, and carbazole poisoned the catalytic sites and thus decreased the ODS activity in the V 2 O 5 /Al 2 O 3 -H 2 O 2 system [20].…”

Ultra‐deep desulfurization of a model fuel using novel VOHPO4 0.5H2O/boehmite catalysts

“…[10][11][12][13][14][15] In addition, the method is more efficient for the removal of heteroaromatic compounds such as thiophene, benzothiophene, dibenzothiophene (DBT) and their alkyl derivatives which cannot be easily removed by the HDS process. [25] Recently Chen and co-workers reported the synthesis and application of VO 2 as a catalyst in the ODS of DBT using tert-butyl hydroperoxide as the oxidant. [16] The combination of hydrogen peroxide as the oxidant and a solid catalyst has led to an effective method for the deep desulfurization of fuels.…”
