Theoretical Assessment of Different Aviation Fuel Blends based on their Physical-Chemical Properties

Abstract

The current study focuses on the theoretical assessment of Sustainable Aviation Fuels (SAFs) obtained by blending traditional jet fuel (Jet A) and different liquids (biodiesel and alcohols) from an analytical point of view. Aeroshell 500 oil was added (5% vol.) to ensure the lubrication of the turbo engine. An in-depth analysis of the physical-chemical properties of Jet A fuel blended with different biodiesels and alcohols was performed. The considered blends consisted of Jet A fuel and biodiesel from palm oil, pork fat, and sunflower and methanol, ethanol, and butanol. All six liquids were mixed with Jet A by 10, 20 and 30%. Flash point, kinematic viscosity, density, freezing point, elemental analysis, and FTIR analysis were conducted for all the blends. The acquired results show the influence of each component on the physical-chemical properties of the blends. Based on the physical-chemical analysis of the blends, conclusions on the latter’s behavior during burning were drawn and the gaseous pollutants resulting from the burning process were examined.
