Abstract—Vapor diffusion was studied from volatile liquids of three brands of UAE gasoline: Super, Special, E+ and a mixture of these brands. The studying was conducted at 50 oC which represent the highest atmospheric temperature in UAE. The diffusion coefficients of Super gasoline ( 98 Octane number) was equal to 6.348 E-07, for special gasoline ( 95 octane number) equal to 7.353 E-07, for E+ (octane number 91) equal to 2.169 E-06, and the mixture of these three brands is 6.302E-07 m2/s. This concluded that super gasoline which has the higher octane number, minimum density, and higher heat of combustion has the lowest diffusion coefficient with air.
Index Terms—Diffusion coefficient, gasoline with different octane number, risk assessment.
