Hydroprocessing of non-edible jatropha oil over sulphided NiMo and NiW catalysts supported on hierarchical mesoporous SAPO-11 was investigated under conditions of 375 − 450 °C, 60–80 bar and 1 h−1 in a fixed-bed reactor. High yield (about 84 wt%) of liquid hydrocarbon products was obtained over all the catalysts, with about 40% diesel and about 40% aviation kerosene, remaining 20% being lighter gasoline range hydrocarbons. Variation of Si content in the support (SAPO-11) did not have very significant impact on the hydroprocessing of jatropha oil. The liquid hydrocarbon products had suitable density and viscosity, and low sulphur content. The catalysts did not show any observable deactivation with time (∼6 days). It is the first report of a single catalyst based process, where the diesel fraction had desired pour point and high cetane value (>100), while the kerosene fraction not only had desired freezing point for Jet A-1 fuel ( |
