Abstract:
The use of alternative and renewable energy resources is in the focus of numerous investigations, to meet challenges such as reduction of greenhouse gas (GHG) emissions and ensuring security of supply at affordable prices. The aviation sector is embedded in the EU policy package although jet fuels constitute presently only about 4¬6 percent to the global crude oil consumption. In 2011, the European Commission has launched the European Advanced Biofuels Flight Path, an industry wide initiative to speed up the commercialization of aviation biofuels in Europe. The development of viable alternative aviation fuels has spurred many research activities. A profound knowledge on jet fuels properties is inevitable, in particular thermophysical and chemical properties, due to the aircraft's needs. Any (synthetic) aviation fuel must be characterized and certified. Furthermore, validated reaction models must be elaborated, which are able to describe and to predict reliably important combustion properties of alternative aviation fuels, to further promote the development of even more sophisticated jet engines. In the present article, an overview is given on the status quo of alternative jet fuels. In addition, some results on investigations of major combustion properties of reformulated kerosenes (FSJF, FT-SPK, FT-SPK+20% 1-hexanol, FT-SPK+50% naphthenic cut) performed within the framework of ALFA-BIRD will be presented. The predictive capability of the detailed reaction mechanism used in simulations will be discussed.
