The invention discloses a method used for preparing a hydrogenation catalyst. The method comprises steps of preparation of an aluminium oxide-based carrier containing silicon and boron, and loading of a hydrogenation active metal; in the step of preparation of the aluminium oxide-based carrier containing silicon and boron, water soluble silicone oil and a soluble boron-containing compound are introduced into an aluminium oxide-based carrier successively or simultaneously, and the aluminium oxide-based carrier containing silicon and boron is obtained via heat treatment. The method is capable of adjusting distribution of acid centers and hydrogenation active centers, achieving coordination effects, and improving comprehensive performance of the hydrogenation catalyst.
