Optimizing In Situ Combustion with Manganese (II) Oxide Nanoparticle-Catalyzed Heavy Oil Oxidation

The combustion front is a crucial parameter in determining the efficiency of situ techniques during enhanced oil recovery. Nowadays, catalytic systems are widely believed to be an efficient tool stabilize front. This study aimed investigate synthesis and activity manganese (II) oxide nanoparticles high-temperature oxidation heavy oils. high low-temperature regions were investigated this study. obtained characterized studied by using X-ray powder diffraction (XRPD), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDX), transmission (TEM), thermogravimetric analysis (TG), nitrogen adsorption desorption measurements, differential calorimetry (DSC) thermal combined with Kissinger isoconversional method. results showed that synthesized had average size 17 ± 4 nm specific surface area 38.2 0.1 m2 g−1, pore distribution ~8 nm. low processes’ activation energies found 98.9 0.7 kJ/mol 151.9 0.6 kJ/mol, respectively, presence nanoparticles. However, these parameters equal 110.1 1.8 142.8 8.3 absence These data processed further calculating corresponding reaction rates. indicated rate was higher nanoparticles, which could play critical role stabilizing process.
