Abstract. The sub- and supercritical water extractions of Athabasca oil sand bitumens were studied using a micro reactor. The experiments were carried out in the temperature range of 360–380 °C, pressure 15–30 MPa and water density 0.07–0.65 g/cm 3 for 0–2 hrs. The extraction conversion of bitumens increased with solvent power and temperature.
