Effect of products based on higher fatty acids on the service properties of jet fuels

Abstract

This article investigates the effects of synthetic fatty acids (SFA)-based products on the service properties of jet fuels obtained by the use of hydrogenation processes. The SFA-based products were added to a sample of T-8 fuel and tests were performed to determine antiwear properties, protection under conditions of water saturation, high-temperature corrosivity, thermal stability under static conditions, thermal stability under dynamic conditions, acidity, iodine number, electrical conductivity, initial crystallization temperature, luminometer number, and effects on rubber. Higher fatty acids and their oligomers are used as corrosion inhibitors in jet fuels produced by various hydrogenation processes. It is determined that the SFA-based products at concentrations up to 0.003% do not have any adverse effects on the service properties of fuels produced by the use of hydrogenation methods of treating; that at 0.005% concentration, all of these products except the still bottoms increase the fuel acidity above the allowable limit; that these products give significant improvements in the antiwear properties of the fuel; and that SFA-based products can be used as protective and antiwear additives for jet fuels produced by hydrogenation processes.
