A composition of matter comprising alumina, at least one compound of titanium and at least one compound of molybdenum is prepared either by the steps of impregnating an alumina support material with an aqueous solution of at least one titanium compound, drying, impregnating the Ti-impregnated material with an aqueous solution of at least one molybdenum compound, drying and calcining; or by the steps of impregnating an alumina support material with an aqueous solution of at least one titanium compound and at least one molybdenum compound, drying and calcining. The compositions of matter of this invention are useful as catalysts for hydrotreating substantially liquid hydrocarbon-containing feed streams (particularly heavy oils) which also contain compounds of nickel, vanadium and sulfur.

A process for preparing a composition of matter comprising alumina as support material, at least one compound of titanium , at least one compound of molybdenum and at least one compound of aluminum, said process comprising the steps of: (A) impregnating a support material consisting essentially of alumina with a solution comprising water, at least one compound of titanium and at least one compound of aluminum; (B) heating the material obtained in step (A) under such conditions as to at least partially dry said material obtained in step (A); (C) impregnating the at least partially dried material obtained in step (B) with a solution comprising water and at least one compound of molybdenum; (D) heating the material obtained in step (C) at a first temperature so as to at least partially dry said material obtained in step (C); (E) heating the at least partially dried material obtained in step (D) at a second temperature, which is higher than said first temperature, so as to activate said at least partially dried material obtained in step (D).
