Preparation method of sustainable aviation fuel hydrogenation catalyst

The invention discloses a preparation method of a sustainable aviation fuel hydrogenation catalyst. The preparation method of the catalyst comprises the following steps: (1) stirring and mixing nickel salt, deionized water and an alcohol solvent for 1-5 hours under the conditions of normal temperature and normal pressure, then adding Al2O3 into the solution, continuously stirring and mixing for 1-10 hours, and finally adding niobium salt, and stirring and mixing for 1-10 hours; and (2) drying the obtained mixed solution for 12-48 hours at the temperature of 80-150 DEG C and normal pressure in an air atmosphere. And (3) roasting the dried catalyst in a muffle furnace in an air atmosphere at normal pressure at 380-450 DEG C for 8-24 hours to obtain the Ni-Nb loaded bimetallic catalyst. The hydrogenation catalyst disclosed by the invention is simple to prepare, low in price, relatively mild and simple in use condition, long in service life and high in activity, and oxygen in bio-based hydrogenated crude oil can
