A fully synthetic aviation fuel or aviation fuel component is provided, 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° 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° C., and a lubricity BOCLE WSD value of less than 0.85 mm. A process for preparing a fully synthetic coal-derived aviation fuel or aviation fuel component by blending a LTFT and a tar derived blend component is also provided, as is a method of producing a coal-derived, fully synthetic aviation fuel or aviation fuel component from coal gasifier tar and an LTFT derived fraction. |
