Transforming Plant Waste into Sustainable Aviation Fuel: Innovations in Continuous Reaction Processes
Washington State University researchers have successfully tested a new method for producing sustainable jet fuel from agricultural waste. This innovative process involves converting lignin-based plant material into a form of jet fuel that could help enhance the performance of environmentally friendly aviation fuels.
Lignin is a key component of plant cells, derived from agricultural byproducts such as corn stover. The researchers developed a process called simultaneous depolymerization and hydrodeoxygenation, which breaks down the lignin polymer and removes oxygen to create lignin-based jet fuel. This fuel could potentially reduce aviation’s Carbon Footprint, minimize contrails, and help meet international carbon neutrality goals.
The team’s recent study marks the first successful test of a continuous process for producing lignin-based jet fuel, using a less processed form of lignin derived from corn stover known as “technical lignin.” This fuel has the potential to replace fossil fuel-derived compounds called aromatics, which are associated with contrails and climate impacts.
By refining their process, the researchers aim to improve efficiency and reduce costs in the production of lignin-based jet fuel. Ultimately, this sustainable fuel could become fully compatible with existing aviation infrastructure and engines, offering a cleaner alternative to traditional fossil fuels. The research was supported by the U.S. Department of Energy and other key partners in the bioenergy and renewable energy sectors.
