Extraction technology for production of environmentally clean diesel and jet fuels

Increasingly rigorous environmental requirements are being imposed on diese l and jet fuels abroad: the concentration of aromatic hydrocarbons in diese l fuel must not exceed 5-10 wt. % [1], and the concentration of naphthalene hydrocarbons in the most widely used jet fuel, Jet A-1, must be below 3 wt . % with a minimum smoke point of 26 mm [2]. Restrictions on the concentrat ion of aromatic hydrocarbons in fuels are also being introduced in Russia: for example, it must be no greater than 20 wt. % in DLECh-V diesel fuel and no greater than 10 wt. % in T-6 ultrasonic jet fuel [3].
