Abstract:
The reforming of heavy oil with supercritical water or subcritical water is accomplished by mixing together supercritical water, heavy oil, and oxidizing agent, thereby oxidizing vanadium in heavy oil with the oxidizing agent at the time of treatment with supercritical water and separate vanadium oxide. The separated vanadium oxide is removed by the scavenger after treatment with supercritical water. In this way it is possible to solve the long-standing problem with corrosion of turbine blades by vanadium which arises when heavy oil is used as gas turbine fuel.
