A highly-dispersed hydrogenation catalyst, a preparation method thereof, and use thereof in the preparation of biofuel from palm oil or other oil are provided. The combination of maleic anhydride-grafted polypropylene (MA-PP) and a silane coupling agent (SCA) is introduced into an aluminum oxide composite carrier through organic amidation to obtain a uniformly-dispersed composite carrier with regular pores. Moreover, through a multi-stage impregnation and roasting process, a particle size of an active component is greatly reduced, and the dispersion of the active component and the number of active sites are improved. A hydrogenation catalyst with high hydrothermal stability, high hydrogenation activity, and long life is prepared based on the composite carrier with regular pores and used in the preparation of biofuel from vegetable oil or other oil through hydrodeoxygenation (HDO), which has great industrial application value.
