Title:
PROCESS FOR THE CATALYTIC OXIDATION OF SULFUR, NITROGEN AND UNSATURATED COMPOUNDS FROM HYDROCARBON STREAMS
Document Type and Number:
WIPO Patent Application WO2002092726
Kind Code:
A3
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 peroxy-acid 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.
