Abstract
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.
