| With petroleum availability/economics in question due to potential geopolitical and supply issues, alternative sources of aviation jet fuels are being explored. Additionally, environmental concerns have added to the need for a renewable, more eco-friendly aviation turbine fuel. While alternative types of fuel are being researched, such as hydrogen, fuel cells, ethanol, and nuclear, all of these require significant fuel production and delivery infrastructure changes, as well as potential engine/plane redesign. This paper describes our work in developing an economical vegetable-based alternate jet fuel that meets current ASTM D-1655 fuel specifications properties of cold temperature behavior, flow, thermal/oxidative stability, density, viscosity, net heat of combustion, and elastomer seal compatibility. It can be used without significant changes in current fuel production or delivery infrastructure and works in existing jet engines. These fuel blends contain up to 40% fractionated soybean fatty acid methyl esters with Jet A fuel. A novel fractionation process has been developed that remove high melting fatty acid components, while allowing yields of approximately 80%. This fuel also reduces SOx, CO, sulfate particles and soot emissions. Engine performance testing is currently underway and performance results will also be discussed in the presentation. |
