A method is provided for making a catalyst support, and includes the steps of providing an aqueous suspension of refractory inorganic oxide and refractory inorganic carbide; forming the suspension into droplets; exposing the droplets to a gelling agent whereby the droplets are at least partially solidified so as to provide substantially sphere-shaped portions of refractory inorganic oxide and refractory inorganic carbide; and drying and calcining the sphere-shaped portions so as to provide substantially spherical particles of catalyst support containing refractory inorganic oxide and refractory inorganic carbide. Catalytically active metal phases and hydrogenation processes using the catalyst are also described.

Hydrogenation catalyst with improved textural properties

A process for upgrading a heavy hydrocarbon feed includes the steps of: providing a hydrocarbon feedstock including a fraction having a boiling point greater than or equal to about 320.degree. C.; mixing the feedstock with steam so as to provide a reaction feedstock; providing a catalyst including a first metal selected from the group consisting of Group VIII non-noble metals and a second metal selected from the group consisting of alkali metals, the first and second metals being supported on a support selected from the group consisting of kaolin, alumina, silica, carbon, petroleum cokes and mixtures thereof; and contacting the reaction feedstock with the catalyst at steam conversion conditions so as to provide a reaction product including an upgraded hydrocarbon fraction.
