Abstract
Mandatory environmental regulations have been
legislated all over the world so the top permitted content of
sulfur in diesel is 15 ppm. ODS is the oxidation of sulfur
compounds present in diesel to form sulfoxides and
sulfones. These substances are highly polar and hence
easily removed by extraction with solvent. Oxidant agent
commonly used are peroxides such as hydrogen peroxide
and tert-butylhydroperoxide (Di Giusepe et al., 2009).
Since Diesel is a non-polar liquid while H2O2 is a polar
liquid, a polar solvent is needed. The formed polar products
can be easily removed from the operation unit by liquid liquid extraction. Mesoporous materials have been tried
showing potential catalytic applications. Transition metals
are commonly used as catalyst in ODS such as Mo, Mn,
Sn, Fe, Zn, V and Ti (Cedeño-Caero et al., 2011). In this
work, we propose the application of different supports as
SBA-15, MCM-48, CMK-1 and CMK-3 for the preparation
of Fe-catalysts.
