Study the Toxic Effects of Aromatic Compounds in Gasoline in Saudi Arabia Petrol Stations

Author(s): A. Y. El-Naggar and M. M. Al Majthoub

Two gasoline samples of octane numbers 91 and 95 from Saudi Arabia petrol stations were studied statically and dynamically. This study was achieved at three different temperatures 20oC, 30oC and 50oC representing the change in temperatures of the different seasons of the year. Both the evaporated gases and liquid paraffinic including light aromatic hydrocarbons (BTEX) of gasoline samples inside the tank were subjected to analyze qualitatively and quantitatively via capillary gas chromatography. The stream composition of each gasoline sample was calculated by the combination of the liberated gases and the liquid gasoline fuel inside the car tank. The detailed hydrocarbon composition and the octane number of the studied gasoline samples were determined using detailed hydrocarbon analyzer. The idea of research is indicating the impact of light aromatic compounds in gasoline on the toxic effect of human and environment on the one hand, and on octane number of gasoline on the other hand. Although the value of octane number will be reduced but this will have a positive impact on the environment as a way to produce clean fuel.
