“…According to Jafari et al , adding bioethanol to gasoline reduces the polarization and solution resistance of the metals, which results in increased corrosion rate when exposed. The corrosion rate of aluminum decreases with time as observed in Figure (a) and (b) in all the fuel blends because of formation of oxides in aggressive environment, which act as barriers for corrosion . The similar trend was noticed in the corrosion result of copper, whereas the corrosion rate of mild steel increase with time in E50 and slightly decrease with time in E0 and E25.…”

“…Several researchers studied the corrosion behavior of metals in ethanol and gasoline blends [3][4][5][6][8][9][10][11][12][13][14][15]. Most of the researchers investigated the corrosion behavior of metals, such as ferrous (low and medium carbon steel, chromium carbon steel and stainless steel) [4,5,[8][9][10][11]14,16], copper [4,5,15], aluminum, and aluminum alloys [3,5,6,8,12,14] in ethanol and gasoline blends through electrochemical properties.…”

Moreover, ethanol and gasoline blends, such as E0 (100% gasoline), E5, E10, E15, E20, E22, E85, and E100 (100% ethanol) have been tested in most of the studies at temperature ranging from 18 to 100°C [3][4][5][6][8][9][10][11][12][13][14][15]. None of these studies analyzed the stability and corrosive properties of bioethanol fuel for metals.…”

SUMMARYCorrosive characteristics of lignocellulosic bioethanol on metals, such as mild steel, copper, and aluminum were studied by static immersion test at room temperature. Effect of metals on degradation of fuel properties, such as pHe, total acid number, acidity, density, viscosity, calorific value, flash point, and color changes were evaluated. Moreover, the transformation of water content and oxidation products in the fuel were investigated. Effect of fuel blends on corrosion rate, chemical structure of metals, and morphology of corrosion product were also examined. Results showed that the corrosion of metals in E50 (50% bioethanol and 50% gasoline) is high compared with E25 and E0. Moreover, degradation of fuel properties and compositional changes in E25 and E50 were high compared with E0. The corrosion rate of aluminum in E50 (0.216 mpy) was lower than copper (0.441 mpy) and mild steel (0.487 mpy). Moreover, the corrosion rate of aluminum in E25 (0.096 mpy) was also lower than copper (0.285 mpy) and mild steel (0.297 mpy). It was discovered that corrosion of materials and degradation of fuel properties were 2.4 times high in higher ethanol blends (above E25) compared with lower ethanol blends (up to E25).

“…Steels and other metals will corrode if the water content in the fuel mixture is high enough to promote phase separation. Park et al (2011) examined the effects of dissolved oxygen on the corrosion of aluminum alloy at high temperature (100 ºC) for E20 fuel (a blend of 20 %v/v of anhydrous ethanol in gasoline) by electrochemical tests and surface analyses. They noticed that the water formed by dissolved oxygen in this fuel enhanced the corrosion resistance of the aluminum alloy by promoting the formation of a protective surface film.…”

-The reduction in the availability of fossil fuel increased the search for alternative fuel sources (for example, ethanol). In the Brazilian market, light duty vehicles can be fueled with gasohol (18 up to 27.5 %v/v of anhydrous ethanol in gasoline) and/or hydrous ethanol. To minimize the risk of water-induced phase separation of gasoline-ethanol blends, anhydrous ethanol is blended into gasoline at the distribution terminal, rather than distributing it through pipelines. Pure ethanol can be distributed through pipelines or trucks, and in pipeline cases almost all are not exclusive. To monitor the ethanol quality, several fuel sampling points are indicated: storage tanks, pipelines, and ship, if applicable. For these samples, it is important to evaluate the following parameters indicative of product quality: hydrocarbon and water amount, color, conductivity, and acidity. Monitoring ethanol storage, transport and distribution is important to maintain the ethanol quality until the final consumer.
