| Abstract Scope |
Sustainable and renewable energy sources as alternatives of fossil fuels are getting more and more attention. Bio-oils produced from biomass via fast pyrolysis have been commercially available and used in food and pharmaceutical industries. However, the corrosivity of bio-oils remains as one of the critical challenges for their wide applications. Compared to the commonly used tank materials for crude oils, e.g., carbon steel and stainless steel, duplex stainless steels (DSS) are attractive candidate constructional materials for the storage and transportation of raw pyrolysis oils due to their high strength and corrosion resistance. This study investigates the corrosion susceptibility of DSS in raw pyrolysis oils provided by different suppliers under simulated operating conditions. The corrosion mode and extent are evaluated using weight change methods and advanced microscopy techniques. The results are expected to advance the standards and requirements on the storage and transportation of raw pyrolysis oils. |
