Mainly disclosed are catalysts for hydrotreating hydrocarbon feedstocks and preparation methods thereof. The present invention mainly provides a catalyst comprising at least one Group VIB metal component, at least one Group VIII metal component, about 1wt%-about 30wt%C, preferably about 1wt%-about 20wt%C, More preferably from about 5wt% to about 15wt%C of one or more sulfur-containing organic additives, and a titanium-containing support component, wherein the content of the titanium component, expressed as oxide ( TiO2 ), is about 3wt% in the total weight of the catalyst % to about 60 wt%. The titanium - containing support is formed by coextruding or precipitating a titanium source with an Al2O3 precursor to form a porous support material comprising Al2O3 or by impregnating a titanium source onto a porous support material comprising Al2O3 . |
