ABSTRACT Disclosed is an improved multi-stage process for the hydroconversion of heavy hydrocarbon feedstocks containing asphaltenes, metals and sulfur compounds. The process is characterized by the use of a relatively inexpensive demetallation catalyst in a first reaction zone comprising a Group VIB and/or a Group VIII metal deposed on a high macropore volume inorganic support followed by the use of a desulfurization catalyst in a second reaction zone com- prising a Group VIB and a Group VIII metal on a high macropore volume inorganic oxide support.
