Transformation of dibenzothiophenes model molecules over CoMoP/Al2O3 catalyst in the presence of oxygenated compounds

► Decrease of the activity of model sulfur compounds (DBT and 46DMDBT) whatever the oxygenated compounds. ► Most inhibiting effect by decanoic acid and CO oxygenated compounds. ► Competitive adsorption between sulfur and oxygenates compounds.
