摘要：

In this work, the thermodynamic activation and kinetic study of mineral lubricant oils was accomplished using isothermal and nonisothermal thermogravimetry based on mass loss as a function of time and temperature. The thermodynamic and kinetic behavior of the mineral lubricant oils depends on the atmosphere and heating rates used in TG analysis. The kinetic and thermodynamic results were satisfactory, presenting good correlation, with a linear correlation coefficient close to unit with a low standard deviation.
