Current and potential aviation additives for higher biofuel blends in Jet A-1

Repetto, Sonia; Costello, James F.; Parmenter, David

Abstract

Since a perfect ‘drop in’ fuel that mimics conventional aviation kerosene without the need for blending is unlikely to be developed in the near future, this chapter considers the range of additives available to modify biofuels to meet the rigorous aviation fuel specifications. Approved additives and their mechanism of action are considered here against the short-fall of biofuels. For example, oxygenated fuels contain a higher water content compared to conventional aviation kerosenes; fuel system icing inhibitors, biocides, and corrosion inhibitors could mitigate the detrimental effects created by the presence of water. Hydroprocessed alternative fuels would benefit from antioxidants and lubricity improvers. Potential additives addressing seal swelling capabilities, soot formation, and water content are also explored. Additives can be a cost effective way to improve alternative fuels in order to allow the use of higher blends in aviation; this is a particularly effective approach given that a number of the additives concerned are mandatory for severely hydroprocessed conventional fuels.
