METHOD FOR PRODUCING GASOLINE BASE MATERIAL AND METHOD FOR ADJUSTING VAPOR PRESSURE OF GASOLINE BASE MATERIAL

摘要

To provide a method for efficiently producing the gasoline base material having a high octane number and a low vapor pressure and a method for adjusting the vapor pressure of a light gasoline fraction.SOLUTION: The method for efficiently producing the gasoline base material includes mixing a fraction containing 90 mass% or more of aromatic hydrocarbons having 9 and 10 carbon atoms with the light gasoline fraction and the method for adjusting the vapor pressure of the light gasoline fraction uses the fraction containing 90 mass% or more of the aromatic hydrocarbons having 9 and 10 carbon atoms.SELECTED DRAWING: None
