EU study sheds light on new jet fuel components and their blending behavior
A new study assigned by the EU Commission has analyzed all new conversion technologies currently undergoing ASTM certification and has screened how blending these with fossil jet fuel affects specification criteria of the blend. Lufthansa and the Bundeswehr Research Institute for Materials, Fuels and Lubricants (WIWeB), who carried out the study, conclude that the characteristics of the neat fossil fuel have a great impact on the percentage of alternative jet fuel it can be blended with. Special consideration needs to be paid to aromatic content, density, distillation curve gradients and cold flow viscosity of the neat fuels as well as of the blend. A comprehensive understanding of interdependencies is a prerequisite for using an increasing share of biojet in the future.
