Abstract:
1. A process for the extractive oxidation of contaminants present in raw fuel streams catalyzed by iron oxides, where heteroatomic polar and unsaturated compounds of said streams are oxidized and simultaneously extracted into the aqueous phase by an aqueous slurry of a peroxide in solution/organic acid couple and catalyst based on iron oxides contained in natural limonitic goethite, under acidic conditions, atmospheric pressure and ambient or higher temperature, while a fuel stream is separated from the catalyst, wherein said process comprises contacting a raw naphtha stream under oxidation conditions in the presence of said oxidizing aqueous slurry and reduced limonitic goethite, between 0.01 and 10 wt % based on the raw naphtha stream, in a Fenton-like system, whereby there is obtained a naphtha fuel at higher than 98 wt % yield based on the raw naphtha stream with a low loss by migration to the aqueous phase and with removal of sulfur and nitrogen compounds.
