Abstract
The experiment of the jet fuel fraction through hydrogenation was investigated via hydrogenation in two-stage fixed beds reactor filled with hydrofining catalyst and hydroisomerization catalyst with low-temperature coal tar (LTCT) distillate (<360 °C) as the feedstock. The reaction of coal tar on the catalyst was studied through analyzing the yield of product, the saturation performance, the carbon number distribution and the chemical components of the jet fuel fraction. In current study, the experimental conditions included the temperature at 340∼400 °C, the pressure of 6∼12 MPa and the liquid hourly space velocity (LHSV) of 0.4∼1.0 h−1. The results showed that at a fixed pressure (10 MPa), reaction temperature (380 °C), LHSV (0.8 h−1) and the H2/oil ratio of (1600:1), the yield of the jet fuel fraction and the content of saturated hydrocarbons in the prodcuts were 58.0% and 60.7%, respectively. Finally, by GC-MS analysis, cyclanes and i-alkanes were dominant components in the jet fuel fraction, approximately accounting for 63.08% and 20.25%, respectively.
