ABSTRACT:
The invention pertains to a hydroprocessing catalyst comprising a Group VIB hydrogenation metal component, a non-noble Group VIII hydrogenation metal component, an alkali metal component, and silica. The catalyst has a specific surface area, total pore volume and pore size distribution. The invention also pertains to the use of this catalyst in hydroprocessing of heavy hydrocarbon feedstocks, e.g, in an ebullated bed process.
