  • Publication number: 20230105628
    Abstract: 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 (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 Al2O3 precursor to form a porous support material comprising Al2O3 or by impregnating a titanium source onto a porous support material comprising Al2O3.

  • Patent number: 11524278
    Abstract: 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 (Ti02) 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 Al203 or by impregnating a titanium source onto a porous support material comprising Al203.

  • Publication number: 20220339614
    Abstract: 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 (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 Al2O3 precursor to form a porous support material primarily comprising Al2O3 or by impregnating a titanium source onto a porous support material primarily comprising Al2O3.
