The present invention describes an extractive oxidation process for removing contaminants from hydrocarbon streams using an ionic liquid combined with an organometallic ionic complex of iron(II), which comprises a complex of iron(II) cation with an ionophilic binder, catalyst of iron(II) with ionophilic binder in its molecular structure, oxidation of which is performed with an oxidizing agent and is catalysed by the organometallic iron(II) complex present in the phase of the ionic liquid. Besides maintaining its characteristics of selective solvent of oxidizing compounds, the ionic liquid combined with the organometallic complex of iron(II) with catalytic ionophilic binder of the oxidizing agent, stimulating the reactive phenomenon taking place in the ionic liquid phase, with the effect that the iron remains stable in the ionic liquid phase, without being leached into the oily phase. This measure results in a considerable improvement in removal of the heteroatoms from the hydrocarbon medium.
