Abstract: A novel multifunctional catalytic system, Ni2P/Zr-SBA-15, was synthesized by H2 temperature-programmed reduction of nickel phosphate precursors impregnated in Zr-SBA-15. Zr-SBA-15 was prepared by hydrothermal crystallization. The properties of catalysts for the hydrodeoxygenation of Jatropha Oil were evaluated by a one-step hydrogenation process in a high-pressure reactor. The best preparation parameters were determined. The multifunction of the catalyst includes excellent deoxidation, aromatization and cracking properties. It is worth noting that this product contains higher concentration aviation fuel components, with amount of C8–C16 accounting for more than 60 wt% of the product oil. The content of paraffin hydrocarbons is 79.25 wt%, aromatic compounds accounting for 10.13 wt% (all consisting of monocyclic aromatics), naphthene accounting for 6.72 wt%. The oil density is 811–828 kg/m3. These physical and chemical properties of C8–C16 are consistent with the detailed requirements for aviation turbine fuels containing synthetic hydrocarbons, as specified in ASTM-D7566-2017b. In this study, the aromatic content and density of nonblended bio-based jet fuels were satisfied with criteria and achieved the one-step hydrogenation process for the preparation of higher quality of bio-jet fuel.
