Differential scanning calorimetric study of heavy oil catalytic oxidation in the presence of manganese tallates

Metal tallates are attracting increasing interest in thermal enhanced oil recovery. Biodegraded heavy oil catalytic oxidation was investigated in the presence of manganese tallates. Differential scanning calorimetry (DSC) was used to highlight the effect of manganese tallates on the oxidation of heavy oil. The obtained data have been performed using the Kissinger method based on the isoconversional principle. Strong evidence of manganese tallates effect on heavy oil oxidation was illustrated in the high temperature oxidation region (HTO). The obtained catalyst increased constant rate in this region almost three times more than when reactions occur in its absence. We believe that we have found an innovative and economical solution to enhance heavy oil via in-situ combustion.
