The catalyst for hydrotreating a deasphalted preparation and application

The catalyst for hydrotreating a deasphalted preparation and application thereof, the catalyst comprising an alumina support having a bimodal pore structure containing an alkaline earth metal component, in order to characterize the mercury pressure method, the pore volume of the support is 0.6-1.4 ml of the total pore volume of pores / g, a specific surface area of ​​80-400 m 2 / g, pore diameter 5-20nm total pore volume of 30-55% of the pore volume, the pore volume having a diameter of 100-300nm 15-45 %. Compared with the prior art, the present invention provides a catalyst having a better hydrodemetallization demetallization and asphaltene performance when used in resid hydrotreating.
