In this study, the influence of various metals (iron, cast iron, copper, aluminum) and sunlight on the gum formation rate in Iraqi gasoline fuel (IGF) is studied. Gasoline has been doped with 5 g/100 mL of used metals and various concentrations (5, 10, 15, 20, 25, 30, 35, 40 g/100 mL) of iron metal. Washed gum content has been analyzed employing ASTM D 381 after storage period of 30 days. The results explain that gum formation at 5 μg mL −1 concentration of different metals obeys the following order: iron cost > aluminum > copper > iron. The results explain that the maximum gum content is 24.4 g/100 mL employing cast iron and the minimum content via using iron metal (6.4 g/100 mL). The results prove that the rate gum formation is higher affected by sunlight in comparing with iron, and weaker influence from other metals. The experimental data shows that gum content strongly enhances via increasing of iron content. The highest gum content (21.8 g/100 mL) is at the maximum iron content (40 g/100 mL) but the minimum rate (6.4 g/100 mL) is at minimum iron content (5 g/100 mL). [ABSTRACT FROM AUTHOR] |
