Alumina and silica are commonly used as solid matrix for characterizing the combustion behavior of crude oils by differential scanning calorimetry (DSC) technique. However, the two basic factors, heating rate and total sample mass, were paid less attention in the process of experiments. Our recent study found that they might significantly change the oxidation behavior due to the use of alumina and silica as solid matrix. In this study, the effects of heating rate and sample mass on the combustion behavior of crude...

Air injection techniques (high pressure air injection and in-situ combustion) for enhanced oil recovery (EOR) have attracted extensive attention due to its low cost. Air injection can be applied in many candidate reservoirs including carbonate reservoirs that account for a great proportion of total oil reserves all over the world. Dolomite and calcite are the main minerals of carbonate reservoirs. Therefore, it is necessary to study their effect on the oxidation of crude oil as the oxidation reaction exactly occur...

Petroleum and its derivatives are the main source of energy for industry and domestic consumption. Petroleum hydrocarbons are based on multiple carbon bonds that develop intense and raised complex structures when they bound with other characteristic molecules, hence the latest hydrocarbons have variety of forms and consist of short, medium and long aliphatics, aromatics and polycyclic aromatic hydrocarbons of different proportions. The accidental release of these hydrocarbons into the environment represents a majo...
