Supercritical water and supercritical water partial oxidation treatments were applied to the upgrading of asphalt. Asphalt was converted at 613-673K, 0-0.5g/cm 3 water density under argon or air atmosphere. Under an argon atmosphere and 0.5g/cm 3 water density, both the asphaltene conversion and desulfurization increased with increasing temperature. At 673K, the asphaltene conversion...
Partial oxidative gasification of n-hexadecane (n-C 16 ) and organosolv-lignin (lignin) was studied by use of a batch type reactor in supercritical water: 673K, 0.52cm -3 of water density (40MPa of water pressure at 673K), and 0.3 of O/C ratio for the n-C 16 experiments; 673K, 0.35cm -3 of water density (30MPa of water pressure at 673K), and 1.0...
In this study, we show the results of partial oxidation experiments of n-hexadecane (n-C 16 ) and polyethylene (PE) in supercritical water (SCW). The experiments were carried out at 673 or 693 K of reaction temperature and 5 or 30 min of reaction time using a 6 cm 3 of a batch type reactor. Water density ranged from 0.1 to 0.52 g/cm 3 (water pressure: 20-40 MPa). The loaded...
