In the article questions of working out and using of additives on biofuels for the purpose of prevention of coking on the walls of thermo exchanged devices’ channels in gas-turbine aviation engines are considered. The coking occurrence reasons and distribution of cokes concentration to channel density on its length are described. The selection of components for creation of the multifunctional additive with a condition of a choice of raw materials from the assortment developed by Russian enterprises is conducted.
