Effect of Flow and Dissolved Oxygen on the Compatibility ofPongamia pinnataBiodiesel with Common Construction Materials Used in Storage and Transportation

[摘要] The compatibility ofPongamia pinnatabiodiesel (PBD) and its NaCl blends on aluminium, brass, copper, carbon steel, and mild steel has been studied by static mass loss and rotating cage methods. The effects of dissolved oxygen and flow on the metal corrosion in PBD were also observed. This study confirmed that the copper strip test alone is not enough to determine the fuel property since the corrosion of ferrous metal was found to be high in PBD compared to other metals. The least corrosion rate of aluminium was confirmed by surface morphology and elemental analysis.
