<p>A gas-oil composition obtained by mixing an animal/vegetable fat and/or an ingredient derived from an animal/vegetable fat with a sulfur-containing hydrocarbon compound so as to result in a sulfur content of 1 mass ppm to 2 mass% to obtain a raw oil to be treated and bringing the raw oil into contact with a sulfide catalyst comprising a porous inorganic oxide containing two or more elements and an active metal deposited on the oxide in the presence of hydrogen. It contains 10-80 vol.% fraction having a 95% distillation temperature of 360°C or lower, sulfur content of 10 mass ppm or lower, and oxygen content of 1 mass% or lower. The gas-oil composition has a sulfur content of 10 mass ppm or lower, oxygen content of 1 mass% or lower, fatty acid/alkyl ester content of 3.5 mass% or lower, acid value of 0.13 mg-KOH/g or lower, methanol content of 0.01 mass% or lower, and glyceride content of 0.01 mass% or lower. This gas-oil composition is excellent in life cycle CO2 emission characteristics, ignitability, oxidative stability, and low-temperature flowability.</p> |
