Abstract To study the oxidation behavior of heavy oils, low temperature oxidation experiments under differential temperature and pressure conditions were carried out for both heavy oils (ordinary heavy and ultra-heavy oils) with thermogravimetry (TG–DTG)/differential scanning calorimeter (DSC) analyses. And the results indicated that the differences of physical properties and oxidation reactions for the heavy oils ascribe to the SARA compositions, H/C ratio and specific oxidation path. Owing to the asphaltenes content, the ultra-heavy oil after the oxidation has more obvious coke deposition with lower activation energy demand to make it possible for the in-situ combustion without combustion adjuvants.
