Abstract

The article considers the question of competitive ability of technologies of alternative aviation fuels production and its application in modern transport sector that develops quickly. Modern tendencies in transport sphere concerning the necessity of transition from conventional oil-derived fuel to alternative one for both road and air transport are considered in the article. These tendencies are explained by the limitation of crude oil deposits, from one side and worsening of the state of environment caused by exhaust gases emissions from another side. Moreover, international aviation authorities, such ICAO, IATA determine the necessity of active development and implementation of alternative aviation fuels. The article analyzes variety of available today renewable feedstock and technological processes of its processing, which are used today for production of alternative aviation fuels. Peculiarities of direct ethanol use in blends with motor fuels are shown and necessity of its chemical conversion for use in jet fuels is substantiated. The comparative analysis of characteristics of technological processes of alternative jet fuels production based on biomass was done. Processes of alcohols (ethanol, n-butanol and iso-butanol) production from renewable plant feedstock and processes of its further conversion to alternative jet fuel are considered. Two methods of ethanol production (petrochemical and biochemical) were shown and analyzed; advantages and disadvantages of both methods were presented.

It was shown that today application of alternative aviation fuels produced from alcohols is allowed in blends with conventional oil-derived jet fuels in quantity up to 50 %.
