FULLY SYNTHETIC JET FUEL

摘要

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°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 " 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.
