Effect of Na2CO3 on the Catalytic Degradation of Crude Oil–Polluted Soil by Fenton Heterogène Reaction with Natural Magnetite

Crude-oil production and transport show high soil and water pollution. The principal aim of this research is to analyze the beneficial effect of natural Na 2 CO 3 on the catalytic degradation of crude oil SARA fraction by Heterogeneous Fenton Reaction with natural magnetite. Saturates Aromatics, Resins and Asphaltenes (SARA) analyses and the gas chromatograph coupled with a Flame Ionization Detector (GC-FID) were typically used to analyze the crude oil compounds and the individual n-alkane oxidation. The decomposition of H 2 O 2 in the presence of this magnetite determined by titration with permanganate follows first-order kinetics in the presence of Na 2 CO 3 . Aromatic compounds were degraded with high efficiency; the saturate and the asphaltene fraction are expected to decrease. At the end of the experiment, the chromatogram of the unoxidized crude oil shows the loss of n-alkanes in the C1 to C13 range and the decrease of the alkanes (nC14-C32).
