摘要

Jet fuel was prepared from low-temperature coal tar (LTCT) via two-stage fixed beds that were filled with two commercial catalysts. The effects of temperature (340-400 degrees C), pressure (6-12 MPa) and liquid hourly space velocity (LHSV) (0.4-1.0 h(-1)) on the hydrogenation performance and properties of the product were investigated, while the H-2/oil ratio was maintained at a constant 1600:1 in all cases. In this study, the freezing point and the heat value increased with increasing pressure and LHSV over the catalysts. However, the freezing point decreased and then increased, while the heat value increased and then decreased with the increase of temperature. The jet fuel (180-280 degrees C) fraction was separated from the product and analyzed. The density, the freezing point and the heat value of the jet fuel were 0.815 g mL(-1), -56 degrees C and 42 MJ kg(-1), respectively. The main components of jet fuel were cycloalkanes and isoalkanes. The results showed that the jet fuel obtained from the LTCT had a series of advantages such as lower freezing point and higher heat value.
