摘要：
The Low Temperature Oxidation (LTO) characteristics of SARA fractions isolated from light crude oil were studied applying the static oxidation experiments. The results show that the LTO reaction of SARA fractions can occur when temperature is above 50 degrees. Under reservoir conditions, the oxidation activities of the SARA fractions were resin > aromatics > saturate. The theoretical LTO reaction rate of crude oil calculated based on the SARA oxidation characteristics is in good agreement with the measured value. Therefore, it is an effective method to reveal the LTO mechanism of crude oil by studying the LTO mechanism of SARA fractions.
