Metal tallates are generating a considerable interest as catalysts for thermaly enhanced oil recovery. Meanwhile, In-situ combustion is considered a promising thermally enhanced oil recovery method, it is still viewed as a complicated process due to its multiphasic, multicomponent and multistep reactions occurring within it. In this study we investigated the impact of Mn@Cu tallate on heavy oil oxidation process in order to highlight its effect on stabilizing combustion front using differential scanning calorimetry combined with isoconversional principle for calculating the kinetic parameters of the process. The obtained data have showed that Mn@Cu tallate can play an important role in stabilizing combustion front of in-situ combustion where it decreased the energy of activation of low temperature (LTO) and high temperature oxidation (HTO) regions. As a result, the effective reaction rate constants in both regions increased respectively as well.
