Embodiment approach 1

[0086] Embodiment 1. A catalyst precursor composition comprising at least one metal from Group 6 of the Periodic Table of the Elements, at least one metal from Groups 8-10 of the Periodic Table of the Elements, and comprising at least one The reaction product of an amino group and a first organic compound having at least 10 carbon atoms or (ii) a second organic compound containing at least one carboxylic acid group and at least 10 carbon atoms, which reaction product is not (i) and (ii) the reaction product of both, wherein the reaction product contains additional unsaturated carbon atoms relative to (i) the first organic compound or (ii) the second organic compound, wherein the metal of the catalyst precursor composition arranged in a lattice, and wherein the reaction product is not located within the lattice.

Embodiment approach 2

[0087] Embodiment 2. A method for preparing a catalyst precursor composition containing in situ formed unsaturated carbon atoms, the method comprising; (a) using a An organic compound or a second organic compound containing at least one carboxylic acid group and at least 10 carbon atoms, treated to contain at least one metal from Group 6 of the Periodic Table, at least one metal from Groups 8-10 of the Periodic Table to form an organic-treated pro-catalyst composition; and (b) heating the organic-treated pro-catalyst composition at a temperature of from about 195°C to about 250°C for a time, The time is sufficient for the first or second organic compound to react to form additional in situ unsaturated carbon atoms not present in the first or second organic compound, but the time is not so long that more than 50 wt. % of the first or second organic compound is volatilized, thereby forming a catalyst precursor composition containing in situ formed unsaturated carbon atoms.

Embodiment approach 3

[0088] Embodiment 3. The catalyst precursor composition or method of any one of the preceding embodiments, wherein said at least one metal from Group 6 is Mo, W, or a combination thereof, and wherein said The at least one metal from Groups 8-10 is Co, Ni, or a combination thereof.

Abstract

Described herein is a catalyst precursor composition comprising at least one metal from Group 6 of the Periodic Table of the Elements, at least one metal from Groups 8- 10 of the Periodic Table of the Elements, and a reaction product formed from (i) a first organic compound containing at least one amine group and at least 10 carbon atoms or (ii) a second organic compound containing at least one carboxylic acid group and at least 10 carbon atoms, but not both, wherein the reaction product contains additional unsaturated carbon atoms, relative to the first or second organic compound, wherein the metals of the catalyst precursor composition are arranged in a crystal lattice, and wherein the reaction product is not located within the crystal lattice. A process for preparing the catalyst precursor composition is also described, as is sulfiding the catalyst precursor composition to form a hydroprocessing catalyst.

Description

technical field [0001] This invention generally relates to hydroprocessing catalysts and their preparation. Background technique [0002] While environmental protection regulations require lower levels of sulfur and nitrogen in distillate fuels, refiners are forced to process crude oils that contain larger amounts of these heteroatoms. Additionally, residual S and / or N containing molecules can poison metal or acid sites on catalysts used downstream of the hydroprocessing process, such as in hydrocrackers. Therefore, there is a need to find more efficient desulfurization and / or denitrogenation catalysts, particularly when existing hydroprocessing units are limited by their pressurization capabilities. [0003] Hydrotreating catalysts typically comprise a sulfided Group 6 metal on a refractory support such as alumina, and one or more Group 8-10 metals as promoters. Bulk, unsupported catalysts, are also known. Hydrotreating catalysts particularly suitable for hydrodesulfuriz...
