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