In this study, the oxidation behavior and kinetics of linear alkanes (C20H42, C24H50, C30H62, C32H66, C36H74, C38H78, C50H102, and C54H110) were investigated by high pressure differential scanning calorimetry (HP-DSC). It turned out that only the exothermic peak of low-temperature oxidation (LTO) was observed during the oxidation process of these linear alkanes, which is different from the oxidation behavior of the crude oil. For the crude oil, two exothermic peaks were observed: LTO and high-temperature oxidation (HTO). This means that the linear alkanes barely contributed in the HTO reaction of crude oils. In addition, the exothermic peaks in the oxidation process of all these linear alkanes overlapped each other. They showed almost the same oxidation behavior in terms of the temperature range of reaction as well as the onset and peak temperatures. It seems that the oxidation behavior of the tested linear alkanes was independent of their carbon number. It was also found that increasing pressure resulted...
