Disclosed is a catalyst for use in hydrotreating hydrocarbon feedstoacks and methods of making the same catalyst. Specifically, a catalyst is disclosed comprises at least one Group VIB metal component, at least one Group VIII metal component, an organic additive resulting in a C-content of the final catalysts of about 1 to about 30 wt% C, and preferably about 1 to about 20 wt% C, and more preferably about 5 to about 15 wt% C and a titanium-containing carrier component, wherein the amount of the titanium component is in the range of about 3 to about 60 wt%, expressed as an oxide (TiO2) and based on the total weight of the catalyst. The titanium-containing carrier is formed by co-extruding or precipitating a titanium source with a AI2O3 precursor to form a porous support material primarily comprising AI2O3 or by impregnating a titanium source onto a porous support material primarily comprising AI2O3. Special preference is given to alumina and alumina containing up to and no more than 1 wt% of silica, preferably no more than 0.5 wt% based on the total weight of the support (dry base). |
