Technical application of a ternary alternative jet fuel blend – Chemical characterization and impact on jet engine particle emission

The use of alternative fuels is an essential element in future aviation. There are currently different approaches with regard to fuel production processes and feedstock materials. This requires flexible handling available quantities. mixtures (blends) inevitable for effective usage commercially components. Within the framework project DEMO-SPK approx. 600 t a ternary mixture (multiblend) jet was produced used real airport infrastructure at Leipzig/Halle. Production application were accompanied by extensive R&D activities show that on-spec, semi-synthetic multiblends can be from several synthetic fuels. One important aspect emission soot particles aircraft engines. Multiblend Jet A-1 has been analyzed flow reactor setup regarding formation precursor compounds comparison reference A-1. experiment revealed lower relevant precursors which also corresponds higher hydrogen content compared fuel. engine proven during ground runs A300-600 PW4158 showed particle number mass than difference decreased increasing power settings. In summary, reduced ~ 29 % emitted 37 if ICAO landing-and-take-off cycle evaluation.
