Abstract

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 Na2CO3 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 H2O2 in the presence of this magnetite determined by titration with permanganate follows first-order kinetics in the presence of Na2CO3. 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).
