通过对国产煤F-T合成燃料的组成和性能进行研究,探讨了国产煤F-T合成燃料用于我国喷气燃料馏分的可行性,并为其作为喷气燃料组分使用提供基础研究数据.结果表明,从国产煤F-T合成燃料中截取的煤油馏分主要由链烷烃和一环环烷烃组成,油样中只含有极少的单环芳烃,没有双环和三环芳烃存在.该馏分的密度、冰点等理化指标不符合3号喷气燃料规范要求,虽然尚不能作为喷气燃料使用,但通过改进加工工艺可作为现用喷气燃料的搀兑组分,其低硫、低氮、低芳烃含量以及热安定性好等特点,有助于改善喷气燃料的热安定性,降低污染物排放.

The compositions and properties of Fischer-Tropsch synthetic kerosene fraction from the indirect liquefaction of domestic coal were studied and the feasibility of using this fraction as jet fuel was discussed.The test results showed that this synthetic kerosene fraction was mainly composed of paraffinic hydrocarbons and monocyclic naphthenic hydrocarbons,besides,only a minor amount of single-ring aromatic hydrocarbons was found,two-ring or three-ring aromatic hydrocarbons were non-detectable.Since some indexes of said fraction,such as density,freezing point and flash point,were not satisfied the specifications of 3# Jet Fuel National Standard(GB 6537-2006),it could not be used as jet fuel directly.Due to the characteristics of low in sulfur,nitrogen and aromatics contents,high in thermal stability,this synthetic kerosene fraction could be used as jet fuel blending components by further altering processing routes,which would improve the thermal stability of conventional jet fuel and would reduce exhaust pollution as well.
