Embodiment 1

[0032] This example describes the preparation of alumina carrier with pseudo-boehmite dry rubber powder. The specific surface area of ​​the pseudo-boehmite dry rubber powder is 390m 2 / g, the pore volume is 0.90ml / g.

[0033] According to the weight ratio of pseudo-boehmite dry rubber powder and SB powder of 3:1, mix evenly, add an appropriate amount of acid solution, and HNO in the acid solution 3 The weight concentration is 1.84%, and the rest is distilled water. After rolling for 20 minutes, squeeze the strips with a clover orifice plate with a diameter of 1.9 mm. After drying at 120°C for 4 hours and calcining at 500°C for 3 hours, the resulting alumina carrier strip is marked as A.

Embodiment 2

[0035] The invention prepares a catalyst.

[0036] Use 5g of glycerol to make an aqueous solution, impregnate 100g of carrier A in an equal volume, place it for 2 hours, and treat it at 150°C for 1.5 hours in an air atmosphere to obtain a carrier that supports organics. Use an impregnating solution containing Mo, Ni, and P with equal volume The carrier was impregnated, dried in an air atmosphere at 150°C for 2 hours, and calcined in an air atmosphere at 450°C for 1.5 hours. The catalyst obtained was designated as CAT1.

Embodiment 3

[0038] The invention prepares a catalyst.

Abstract

The invention discloses a preparation method of hydroprocessing catalyst, comprising the following steps of: (1) preparing a porous catalyst carrier; (2) impregnating the catalyst carrier with organic compound solution; (3) carrying out heat treatment by utilizing the organic compound additive supported carrier obtained by the step (2); (4) supporting active metal component onto the organic matter supported carrier, so as to obtain a catalyst precursor; and (5) roasting the catalyst precursor obtained by the step (4), so as to obtain the hydroprocessing catalyst. In the preparation method disclosed by the invention, the organic matter is uniformly supported onto surface of the catalyst carrier, and then the active metal is supported, operational performance of the catalyst is improved, especially aggregation of the catalyst in a roasting process is reduced, and dispersion of the active metal of the catalyst is improved.

Description

Technical field [0001] The invention relates to a preparation method of a hydroprocessing catalyst, in particular to a preparation method of a high-activity hydroprocessing catalyst. Background technique [0002] Crude oil and distillate oil obtained from crude oil contain impurities such as sulfur, nitrogen, oxygen and metals. The presence 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. In the secondary processing of oil products, the presence of impurities such as sulfur, nitrogen, oxygen and metals can poison the catalyst. Therefore, removing the above impurities is an important process in oil processing. Distillate hydrotreating refers to the process in which feed oil and hydrogen come into contact with the catalyst at a certain temperature and pressure to remove impurities and saturated with aromatics. [0003] Typical hydrotreating catalysts are oxides of metals of groups ...
