Abstract:
1. A method of operating a gas turbine which comprises: providing a heavy oil containing at least one of vanadium and sulfur; reacting said heavy oil with water which is heated to 300° C. to 500° C. and pressured to 10 MPa to 30 MPa by utilizing the heat of exhaust gas from said gas turbine, and then bringing said heavy oil, along with said water, into contact with a scavenger for scavenging vanadium and/or sulfur in the heavy oil to thereby eliminate vanadium and/or sulfur from the heavy oil, thereby producing a reformed oil suitable for said gas turbine, wherein the vanadium concentration of said reformed oil is reduced to 0.1 ppm or less; and supplying said reformed oil to said gas turbine.
