How to remove the sulfone species formed in oxidative desulfurization (ODS) of middle distillates through an efficient method is crucial in a successful ODS process. In this study, the solubility of dibenzothiophene (DBT) sulfone in different hydrocarbon streams was assessed and investigated in detail, and the adsorptive removal of DBT-sulfone dissolved in a model hydrocarbon stream on activated carbon...
A study in oxidation kinetics of dibenzothiophene (DBT), 4-methyldibenzothiophene (4-MDBT), and 4,6-dimethyldibenzothiophene (4,6-DMDBT) in a model fuel with cumene hydroperoxide as an oxidant over a MoO3/γ-Al2O3 catalyst was carried out. Effects of the catalyst, hydroperoxide-to-sulfur molar ratio, reaction time, and reaction temperature on the oxidation were investigated in detail. The oxidation...
A high-performance nickel-based sorbent was developed by loading nickel on a mesoporous molecular sieve, MCM-48, for adsorptive desulfurization (ADS) of commercial ultra low sulfur diesel (ULSD) for fuel cell applications. The prepared sorbents were characterized by the N 2 adsorption–desorption, X-ray diffraction (XRD), H 2 chemisorption, and transmission electron microscope (TEM),...
