[0016] (1) prepare porous catalyst carrier;

[0017] (2) Step (1) is used to obtain a porous catalyst carrier loaded active metal component and one or more non-sulfur-containing organic additives, which contain at least two hydroxyl groups and 2-20 carbon atoms of organic compounds;

[0018] (3) adding one or more sulfur-containing organic additives to the material obtained in the above step (2);

[0019] (4) Steps (2) and (3) of the above-mentioned catalyst preparation process may include one or more drying ...

Embodiment 1

[0036] The catalyst was prepared using mercaptoformic acid.

[0037] Reference catalyst CA was prepared as follows. Catalysts were prepared using gamma-alumina carrier ZT (1.2mm, clover) with the following properties:

[0038] Pore ​​volume: 0.75mL / g

[0039] Specific surface area: 320m 2 / g

[0040] Bulk density: 0.55g / mL

[0041] The gamma-alumina carrier was impregnated with an equal volume of aqueous impregnating solution containing an appropriate amount of molybdenum trioxide, nickel carbonate and phosphoric acid, and the impregnated carrier was dried at 100°C for 16 hours, and then the dried strip was calcined at 470°C for 3 hours in an air atmosphere. The prepared catalyst contains 12(w)% molybdenum (calculated as oxide), 3.2(w)% nickel (calculated as oxide) and 2(w)% phosphorus (calculated as P 2 o 5 count).

[0042] Catalyst BA of the present invention is to impregnate carrier ZT with the equal volume of the aqueous solution that contains appropriate amount of me...

Embodiment 2

[0056] The catalyst was prepared using methyl thioglycolate.

[0057] The reference catalyst CB impregnated the γ-alumina carrier with an equal volume of an aqueous impregnating solution containing an appropriate amount of molybdenum trioxide, nickel carbonate, phosphoric acid and diethylene glycol, and dried the impregnated carrier at 100°C for 16 hours. The prepared catalyst contains 12(wt)% molybdenum (calculated as oxide), 3.2(wt)% nickel (calculated as oxide) and 2(wt)% phosphorus (calculated as P 2 o 5 count). The amount of diethylene glycol is the molar ratio of diethylene glycol to the amount of active metal.

[0058] Catalyst BB of the present invention is to impregnate carrier ZT with equal volume of aqueous solution containing appropriate amount of methyl mercaptoacetate, dry under the condition of table 4, then with equal volume of water impregnating liquid containing appropriate amount of molybdenum trioxide, nickel carbonate, phosphoric acid and diethylene glyc...

Abstract

The present invention relates to a preparation method for a hydrotreating catalyst, which induces organic additives before, in the middle of or after inducing the active metal components on a porous catalyst carrier; wherein, at least one organic additive is an organic additive containing sulfur; then carries out one or a plurality of drying steps after inducing the active metals or the organic additives with a drying temperature lower than 300 DEG C but without baking processes in the preparation process of the catalyst. The use property of the hydrotreating catalyst prepared by the method of the present invention can be further improved and the method can be applied to various hydrotreating catalyst processes.

Description

technical field [0001] The invention relates to a preparation method of a hydrogenation treatment catalyst, in particular to a preparation method of a high activity hydrogenation treatment catalyst. Background technique [0002] Crude oil and distillates derived from crude oil contain impurities such as sulfur, nitrogen, oxygen and metals. The existence of these impurities not only affects the stability of the oil, but also emits SO during use. X , NO X and other harmful gases pollute the environment. During the secondary processing of oil products, the presence of impurities such as sulfur, nitrogen, oxygen and metals can poison catalysts. Therefore, removing the above-mentioned impurities is an important process in oil processing. Distillate oil hydrotreating refers to the process of contacting raw oil and hydrogen with a catalyst at a certain temperature and pressure to remove impurities and saturate aromatics. [0003] Typical hydrotreating catalysts are metal oxide...
