<p>As a gas oil composition which results from an animal or vegetable fat or oil and which is excellent in life-cycle COemission characteristics and lubrication performance, a gas oil composition specified in T95, sulfur content, oxygen content, fatty acid alkyl ester content, total acid number, glyceride content, and so on is provided, which composition is obtained by adding 50 to 300ppm by mass of a lubricity improver to a fraction produced by bringing an oil to be treated which oil is obtained by mixing an animal or vegetable fat or oil and/or a component resulting from an animal or vegetable fat or oil with a sulfur-containing hydrocarbon in such an amount at to give a sulfur content of 1ppm by mass to 2% by mass into contact with a catalyst consisting of a porous inorganic oxide and a group 6A metal and/or a Group 8 metal which are supported on the oxide under prescribed hydrogen conditions.</p> |
