Hydrodeoxygenation catalyst for bio-jet fuel precursor, preparation method and application

Abstract

The application discloses a hydrodeoxygenation catalyst for bio-jet fuel precursor, a preparation method and application thereof, and belongs to the technical field of biomass liquid fuel; the preparation method comprises the following steps: dissolving ZrOCl2 and (NH4)2HPO4 in water respectively, mixing the two solutions under stirring, adding ammonia water drop by drop, placing the obtained solid mixture in an autoclave after sufficient stirring, and heat preservation and heating; then, the zirconium phosphate carrier is obtained through filtering, washing, drying and calcining; the metal salt and NbCl5 are dissolved in water at the same time, then low-carbon dihydric alcohol is added, and stirring is uniformly performed; the zirconium phosphate carrier is ultrasonically dispersed in the solution, water is evaporated under stirring, and then the zirconium phosphate catalyst loaded with the metal and NbCl5 is prepared through drying, calcining and hydrogen atmosphere reduction. The hydrocarbon yield of the catalyst catalyzed bio-jet fuel precursor hydrodeoxygenation refining product is high, the composition is relatively rich, and the yield and quality of the bio-jet fuel product can be improved.
