|Production of fuels for aircraft engines is one of the prior branches of the world oil-processing industry. First of all it is explained by the increase of Aircraft Park. About 5.5 thousand barrels of fuel for Air Jet Engines (AJE) are produced and consumed all over the world daily. Requirements to quality of fuels for AJE are initially much higher than for gasoline and diesel fuels. Quality of fuels for AJE comparing to other petroleum products depends mostly on the oil origin and boiling temperatures of oil fractions obtained during atmospheric distillation. Some amount of fuel for jet engines is obtained by catalytic destructive processing of straight run or vacuum distillates and catalytic cracking products in a presence of hydrogen.
In recent years, some amount of fuels for AJE is produced from alternative raw materials such as coal, natural gas, oil sands, oil shale, and biomass. Technologies used for processing of these types of feedstock allow obtaining of high-quality fuel, with the possibility to vary certain parameters if required. However, these technologies are quite energy-intensive and difficult for realization. So, refining of base kerosene oil fractions requires hydrotreating and various destructive methods; at the same time, obtaining of basic fractions from non-oil derived feedstock, in addition to mentioned stages, needs pyrolysis, FT-synthesis, gasification etc. Nevertheless, the limitation of the worlds oil deposits still promotes development of alternative technologies for jet fuels production.
