Abstract
The present invention pertains to a catalyst comprising 7–20 wt. % of a Group VIB metal component, calculated as trioxide on the weight of the catalyst, and 0.5 to 6 wt. % of a Group VIII metal component, calculated as oxide on the weight of the catalyst, on a porous inorganic carrier. The catalyst has a specific surface area of 100–180 m/g, a total pore volume of at least 0.55 ml/g, at least 50% of the total pore volume in pores with a diameter of at least 20 nm (200 Å), 10–30% of the total pore volume in pores with a diameter of at least 200 nm (2000 Å), and 0–1% of the total pore volume in pores with a diameter above 1000 nm (10000 Å). The catalyst is particularly suitable for the hydroprocessing of heavy hydrocarbon feeds of which at least 50 wt. % boils above 538° C. (1000° F.). It is especially advantageous for the hydroprocessing of feedstocks of which at least 80 wt. % boils above 538° C. (1000° F.).
