A catalyst for hydrodemetalization of heavy oil, especially residuum oil, and a process for preparing the same, wherein said catalyst comprises the metal elements of Groups VIII and/or VIB as active components supported on an alumina carrier having large pores. The total pore volume of said carrier is in the range of 0.80&tilde;1.20 ml/g (by mercury porosimetry method), the specific surface area in the range of 110&tilde;200 m,/g, the peak pore diameter in the range of 15&tilde;20 nm, and the bulk density in the range of 0.50&tilde;0.60 g/ml. In the process of the invention, a physical pore-enlarging agent and a chemical pore-enlarging agent are added simultaneously during the mixing of the pseudoboehmite to a plastic mass, then extruding, drying, calcining, the carrier is obtained, then impregnating with active components by spraying onto the carrier, after drying and calcining, the catalyst is obtained. The catalyst of the invention is suitable for the hydrodemetalization and/or hydrodesulfurization of heavy oil, particularly residuum oil.
