摘要：PROBLEM TO BE SOLVED: To provide a kerosene composition excellent in combustibility, oxidation stability, and life-cycle characteristics. SOLUTION: The kerosene composition is obtained by mixing 10-90 vol.% kerosene base of a low environmental load type and 90-10 vol.% kerosene fraction obtained by the refining of, e.g., crude oil. The kerosene base is produced by hydrotreating, as a raw material, an animal/vegetable fat in which the proportion of constituent fatty acids having an alkyl group with 10-14 carbon atoms is 60 mass% or higher. The hydrotreating is conducted in the presence of hydrogen using a catalyst which comprises a porous inorganic oxide containing two or more elements selected among aluminum, silicon, zirconium, boron, titanium, and magnesium and, deposited on the inorganic oxide, one or more metals selected among the elements in group 6A and group 8 of the periodic table, under the conditions of hydrogen pressure of 2-13 MPa, liquid hourly space velocity of 0.1-3.0 h<SP>-1</SP>, hydrogen/oil ratio of 150-1,500 NL/L, and reaction temperature of 150-480°C. The kerosene composition has an initial boiling point of 140°C or higher, final boiling point of 300°C or lower, flash point of 40°C or higher, sulfur content of 10 mass ppm or lower, 15°C density of 740-820 kg/m<SP>3</SP>, smoke point of 23 mm or more, and peroxide value less than 1 mass ppm.
