Sustainable Aviation Fuel Prescreening

Fuels derived from sustainable feedstocks have significant potential to reduce greenhouse gas emissions associated with aviation. These alternative aviation fuels need to meet comprehensive safety and compatibility requirements established by an ASTM committee to achieve approval. As described in the paper below, two-dimensional gas chromatography is being used to determine the composition and size distribution of alternative fuels, and Monte Carlo sampling is subsequently performed with a hydrocarbon database to predict properties that are important for combustor operability. This Tier α provides an early, rapid, and cost-effective evaluation for SAF candidates that requires minimal fuel volumes
