Abstract:
1. A method for producing gas turbine fuel oil from feed oil with increased yields, comprising: an atmospheric distillation step of subjecting crude oil acting as said feed oil to atmospheric distillation to separate said crude oil into light oil and atmospheric residue oil; a first hydrotreating step of contacting the light oil produced in said atmospheric distillation step with pressurized hydrogen in the presence of a catalyst in a lump, to thereby carry out an impurity removal treatment, resulting in obtaining refined oil; a first separation step of separating said atmospheric residue oil into a light oil matter and a heavy oil matter; said first separation step being selected from the group consisting of vacuum distillation, solvent deasphalting, thermal cracking and steam distillation; and a second hydrotreating step of contacting the light oil matter produced in said first separation step with pressurized hydrogen in the presence of a catalyst, to thereby carry out an impurity removal treatment, resulting in obtaining refined oil; said refined oil produced in said first and second hydrotreating steps being the one and only product obtained and used as the gas turbine fuel oil; the gas turbine fuel oil which is refined oil thus obtained in said first and second hydrotreating steps being 4 cSt or less in viscosity at 100° C., containing alkaline metal in an amount of 1 ppm or less, lead in an amount of 1 ppm or less, V in an amount of 0.5 ppm or less, Ca in an amount of 2 ppm or less and sulfur in an amount of 500 ppm or less, and being produced with yields of 65% or more based on said feed oil.
