The invention relates to the technical field of catalysts, in particular to an ellipsoidal alumina-supported metal catalyst and a preparation method and application thereof. The invention discloses an ellipsoid alumina supported metal catalyst, comprising ellipsoid alumina and metals supported on the ellipsoid alumina; the long axis of the ellipsoid alumina is 2-3 μm, and the short axis is 1-1.5 μm μm, and the specific surface area is 150 m 2 /g to 200 m 2 /g. The ellipsoidal alumina-supported metal catalyst provided by the invention has a higher specific surface area, so that the metal dispersion degree on the alumina surface is improved, thereby providing more active sites, which is beneficial to the hydrogen on the surface of the metal particles in the catalytic hydrogenation reaction activation. Therefore, the alumina-supported metal catalyst with the ellipsoidal alumina structure of the present application has higher catalytic activity and stability for the catalytic hydrogenation of condensed aromatic hydrocarbons. |
