Abstract
Disclosed is an improved process for the hydrodemetallization, hydrodesulfurization, hydrodenitrogenation, and hydroconversion of a hydrocarbon feedstock containing asphaltenes, metals and Shell hot filtration solids precursors. The process utilizes a catalyst mixture wherein one component of the mixture is a relatively small pore catalyst and another component is a catalyst that possesses a relatively large amount of macropore volume.
