Lignin-derived jet fuel displays a superior heat of combustion, higher seal swell properties and a much lower aromatic content compared to Jet-A.
Bin Yang, professor in the Biological Systems Engineering Department at Washington State University (WSU) in Richland, WA, says, “Besides using jet fuel, other propulsion options such as batteries and fuel cells are not suitable for use in long-distance airplance travel in the near future (less than 30 years). This places the aviation industry in the position of needing to find a sustainable alternative to Jet-A. One big concern with using the incumbent jet fuel is its aromatic content, which varies from approximately 8% to 25% by volume, which is key to the density and seal swell characteristics of jet fuel but increases engine soot production. Some approved alternative jet fuels, such as synthetic paraffinic kerosene (SPKs), need the addition of aromatics and others contain aromatics. Ultimately, the aviation industry is seeking a 100% sustainable aviation fuel that produces no emissions.”
