This invention provides supported catalysts comprising a carrier, phosphorus, at least one Group VI metal, at least one Group VIII metal, and a polymer. In the catalyst, the molar ratio of phosphorus to Group VI metal is about 1:1.5 to less than about 1:12, the molar ratio of the Group VI metal to the Group VIII metal is about 1:1 to about 5:1, and the polymer has a carbon backbone and comprises functional groups having at least one heteroatom. Also provided are a process for preparing such supported catalysts, as well as methods for hydrotreating, hydrodenitrogenation, and/or hydrodesulfurization, using supported catalysts.

Supported hydrotreating catalysts having enhanced activity

Generally, it is disclosed a catalyst for use in a hydrotreating hydrocarbon feedstocks and the method of making such catalyst. It is generically provided that the catalyst comprises at least one Group VIB metal component, at least one Group VIII metal component, 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 of one or more sulfur containing organic additive 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 (Ti0) 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 Al203 precursor to form a porous support material comprising Al0or by impregnating a titanium source onto a porous support material comprising Al0.

Hydrotreating catalyst with a titanium containing carrier and sulfur containing organic additive

Disclosed is a catalyst for use in hydrotreating hydrocarbon feedstocks 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 (TiO) 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 AIOprecursor to form a porous support material primarily comprising AIOor by impregnating a titanium source onto a porous support material primarily comprising AIO. 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).

Hydrotreating catalyst with a titanium containing carrier and organic additive

The current invention relates a bulk catalyst precursor (i.e. no support material is added as such) comprising Ni and Mo and/or W and an organic component, wherein the molar ratio of C:(Mo+W) ranges from 1.5 to 10. The bulk catalyst precursor is prepared from a mixture of metal-precursors with an organic agent. The organic agent is partly decomposed to form a mixed metal-oxide/C phase which is in effect the bulk catalyst precursor. This bulk catalyst precursor (i) is effectively insoluble in water (ii) does not have any appreciable pore volume or surface area and (iii) does not contain a (nano)crystalline metal-oxide phase as characterized by XRD. A bulk catalyst is made from the bulk catalyst precursor.
