Abstract (en)
[origin: EP1686166A1] An unleaded gasoline composition having a sulfur content of 1 mass ppm or less and exhibiting sufficient driving performance and a method thereof are provided. A method for producing an unleaded gasoline composition having a sulfur content of 1 mass ppm or less and a research method octane number of 89.0 or more, which comprises a step of subjecting a cracked naphtha fraction having a 5 vol % distillation temperature of 25°C or higher, a 95 vol % distillation temperature of 210°C or lower, an olefin content of 5 mass % or more and a diene value of 0.3 g/100 g or less to a desulfurization treatment, and a blending step of mixing the above resultant desulfurized cracked naphtha fraction with another gasoline base materials; and an unleaded gasoline composition which has a research method octane number of 89.0 or more, a 50 vol % distillation temperature of 105°C or lower, an olefin content of 10 vol % or more, a total sulfur content of 1 mass ppm or less, and a percentage of a thiophene type sulfur compound in the total sulfur content of 50 mass % or more as sulfur.
