摘要：

Present study investigates thermal behavior of two heavy crude oils with different A degrees API values by simultaneous thermogravimetry-differential scanning calorimetry-fourier transform infrared spectroscopy (TG-DSC-FTIR), and an evaluation of the chemical element levels present in the oils' ashes was done by energy dispersive X-ray fluorescence spectrometry. TG and DSC curves were obtained for two samples in nitrogen atmosphere. Among all inorganic components evaluated, the highest concentration in the two oils was SO3. Thus this study may contribute to a better understanding of the thermal behavior of heavy crude oils and their composition.
