Abstract
A process for the catalytic oxidation of sulfur and nitrogen contaminants as well as unsaturated compounds present in a hydrocarbon fossil oil medium is described, the process comprising effecting the oxidation in the presence of at least one peroxide, at least one acid and a pulverized raw iron oxide. The process shows an improved oxidation power towards the contaminants typically present in a fossil oil medium, this deriving from the combination of the peroxyacid and the hydroxyl radical generated in the reaction medium due to the presence of an iron oxyhydroxide such as a limonite clay, which bears a particular affinity for the oil medium. The process finds use in various applications, from a feedstock for refining until the preparation of deeply desulfurized and deeply denitrified products.
