Abstract:
Biodiesel is derived from biomass, organic matter coming from vegetables or animals, which can be used for energy production and therefore is considered a biofuel. Because it is less polluting and constitutes a source of renewable energy, biodiesel has an important role in the fuel sector. The biodiesel by itself or mixed in different proportions with diesel can replace the diesel oil whether in automotive engines (trucks, tractors, vans, cars) or in stationary engines (electricity or heat generators). However, data on the corrosion of metals when in contact with biodiesel/diesel blends as well as information about the influence of the metallic corrosion products in biodiesel/diesel blends quality are still poorly understood. Therefore, the objective of this work was to study the compatibility between biodiesel/diesel blends and different metallic materials with focus on the blend quality and on the integrity of facilities used during transportation and storage. For this purpose, the chosen metallic materials were carbon steel (UNS¹ n.G120200) copper (UNS n.C11000), brass (copper alloy UNS n.C26800), aluminum (UNS n.A91100) and stainless steel (UNS n.S31600). The study was conducted through laboratory immersion tests
