<p><P>PROBLEM TO BE SOLVED: To obtain a gas oil composition that comprises a low environmental load type gas oil base produced from triglyceride-containing hydrocarbons being animal and vegetable oils and fats and animal and vegetable oil and fat-derived components as raw materials and has excellent life cycle CO<SB>2</SB>discharge characteristics and lubrication properties. <P>SOLUTION: The gas oil composition is obtained by bringing a treated oil prepared by mixing animal and vegetable oils and fats and/or an animal and vegetable oil and fat-derived components with a sulfur-containing hydrocarbon compound so as to have a sulfur content of 1 mass ppm-2 mass% into contact with a porous inorganic oxide containing two or more kinds of elements selected from aluminum, silicon, zirconium, boron, titanium and magnesium and a catalyst containing one or more kinds of metals selected from elements of the group 6A and the group 8 supported on the porous inorganic oxide in the presence of hydrogen under a hydrogen pressure of 2-13 MPa, at a liquid space velocity of 0.1-3.0 h<SP>-1</SP>, at a hydrogen oil ratio of 150-1,500 NL/L at a reaction temperature of 150-480°C to produce a fraction and adding 50-300 mass ppm of lubricity improver (LI) and has a 95% distillation temperature of≤360°C, a sulfur content of≤10 mass ppm, an oxygen content of≤1 mass%, a fatty acid alkyl ester content of≤3.5 mass%, an acid value of≤0.13 mgKOH/g, a methanol content of≤0.01 mass%, a glyceride content of≤0.01 mass% and a wear scar diameter (WS 1.4) by HFRR of≤460μm. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
