“…Coal-based alternative jet fuels refer to the liquid fuels obtained from solid coal, using coal as raw material. As early as 1978, the National Aeronautics and Space Administration (NASA) made an evaluation of the possibility of the application of the coal-based synthetic fuels in aviation [1]. Large-scale applications of coal-based jet fuels have many advantages.…”

There are mainly four pathways to get liquid fuels from the coal including the direct liquefaction process, the Fischer-Tropsch process, coal-tar refining, and pyrolysis process. The characteristics of these four processed have been described. As the first two pathways are considered to be promising, the characteristics of these two types of coal-based jet fuels are discussed and the component characteristics of coal-based synthesis fuels are investigated, respectively. The component characteristics of coal-based jet fuels are compared with the traditional petroleum-based jet fuels. There are large differences between the properties of the coal-based jet fuel via direct and indirect liquefaction pathways. Comparing with the conventional petroleum-based jet fuel, the coal-based jet fuel via direct liquefaction pathway has the higher aromatics content, while the fuel via indirect pathway (F-T process) has more paraffin and nearly no naphthenes or aromatics. In additional, the carbon numbers of the coal-based synthesis jet fuels are compared with the conventional petroleum-based jet fuel.

“…As was pointed out in reference (5), an insulating material may be necessary in the construction of the first stage stator blades to reduce the internal thermal gradient. The author of reference (1) concluded that fuel cooling of the compressor bleed air would yield greater potential for turbine cooling than improvements in cooling design or cooling method alone.…”
