WebFeb 1, 1999 · Using near-critical or supercritical water (SCW) instead of organic solvents in chemical processes offers environmental advantages and may lead to pollution prevention. Interest in doing chemistry in SCW is not entirely new, however. WebPartial oxidation of bitumen was examined in supercritical water from 653 to 723K at a water/oil ratio from 0 to 3 and up to 5.1MPa of initial air pressure. The contents in the reactor were separated into water rich phase and oil rich phase. Most of oxygen was quickly consumed within 30min and the main gases produced were CO, CO2 and methane. dfki germany computer visionWebSupercritical water has a density between that of water vapor and liquid at standard conditions, and exhibits high gas -like diffusion rates along with high liquid -like collision rates. In addition, the behavior of water as a solvent is altered (in comparison to that of subcritical liquid water) - it behaves much less like a polar solvent. churning up meaning
