Abstract
The work is devoted to the investigation of low-temperature properties of alternative jet fuels mixed with bio-additives derived from rapeseed oil, methanol and ethanol. For this work, a modification of conventional jet fuel from rapeseed oil, methanol and ethanol was chosen to develop alternative jet fuels. The main low-temperature characteristics – freezing point and pour point of conventional jet fuel and three types of bio-additives were identified and compared with the requirements for conventional Jet A-1 fuel. The influence of bio-additives from rapeseed oil, methanol and ethanol on low-temperature characteristics of new jet fuels has been studied and explained. The necessity of studying new technologies is grounded.

Bio-additives based on FAME and FAEE of RO are characterized by significantly higher values of pour point (PP) comparing to conventional JF (Table 1.)
Summary
The jet fuel Jet A-1, the product used in today's airliners, has been largely refined from crude oil feedstock. The aviation industry became aware of emissions and its contribution to climate change. It has raised concerns over future supply security and operational costs. These factors have led to interest in the development of product produced from alternative sources. Advancement in process technology is providing alternative means of producing traditionally distilled crude products, through the conversion of coal, gas or biomass. The processing techniques provide production of fuels, which have similar properties to conventional Jet A-1 fuel
