全合成的喷气燃料
摘要：
本发明提供了一种全合成的航空燃料或航空燃料组分，具有：总环烷烃含量大于30质量％；环烷烃类与异链烷烃类的质量比大于1并小于15；密度(15℃)大于0.775g.cm-3但小于0.850g.cm-3；芳香烃含量大于8质量％但小于20质量％；冰点小于-47℃；润滑性BOCLE WSD值小于0.85mm。本发明还提供了通过将一种LTFT衍生的混合组分和一种焦油衍生的混合组分混合来制备一种煤衍生的全合成航空燃料或航空燃料组分的方法。本发明还延及一种由煤气化产生的焦油及LTFT衍生馏分来制备由煤衍生的全合成航空燃料或航空燃料组分的方法。
摘要（英）：

The invention provides a fully synthetic aviation fuel or aviation fuel component having : '' a total naphthenic content of more than 30 mass % '' a mass ratio of naphthenic to iso-paraffinic hydrocarbon species of more than 1 and less than 15 '' a density (at 15 DEG C) of greater than 0.775 g.cm-3, but less than 0.850 g.cm-3 '' an aromatic hydrocarbon content of greater than 8 mass %, but less than 20 mass % '' a freezing point of less than - 47 DEG C '' a lubricity BOCLE WSD value of less than 0.85mm. The invention further provides for the preparation of a fully synthetic coal-derived aviation fuel or aviation fuel component by blending a LTFT and a tar derived blend component. The invention extends to a method of producing a coal-derived, fully synthetic aviation fuel or aviation fuel component from coal gasifier tar and an LTFT derived fraction.
