Abstract
A process for hydrotreating substantially liquid hydrocarbon containing feed streams (particularly heavy oils) which also contain compounds of nickel, vanadium and sulfur employing a catalyst composition 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.
