Hydrogenation asphaltene removal catalyst and preparation and use thereof

The invention discloses a hydrogenation asphaltene removal catalyst and preparation and use thereof, the hydrogenation asphaltene removal catalyst comprises an alkaline earth metal-containing alumina carrier which is characterized by the mercury injection method, the carrier pore volume is 0.6-1.4 ml / g, the specific surface area is 80-400 m / g, the volume of the pore with the diameter of 5-20nm accounts for 30-55% of the total pore volume, and the volume of the pore with the diameter of 100-300nm accounts for 15-45% of the total pore volume. Compared with the prior art, the catalyst has better hydrogenation asphaltene and metal removal performances when used in residual oil hydrogenation treatment.
