A Du Pont differential scanning calorimeter (DCS) and thermogravimetric analyzer (TGA) has been used to characterize the pyrolysis and combustion properties of two heavy crude oils. In pyrolysis runs, temperature ranges where distillation and visbreaking occur were identified. In combustion with air three different reaction regions were identified, known as low temperature oxidation, fuel deposition, and high temperature oxidation. DSC-TGA curves have also been used to determine the heat values and reaction parameters of crude oils.
