Embodiment 1

[0108] Take 100g of pseudo-boehmite powder produced by Catalyst Changling Branch, add 4.0g of methyl cellulose, 3.0g of scallop powder and 95mL of deionized water, fully stir and mix evenly, after kneading evenly by an extruder, extrude to form A wet form of aluminum hydroxide is obtained. The wet aluminum hydroxide molded product was placed in an oven at 150°C and dried for 12 hours to obtain a hydrated alumina-containing molded carrier S1. The radial crushing strength, water absorption rate and δ value (strength loss rate) of the molded carrier S1 after drying were measured, and the results are listed in Table 1.

Embodiment 2

[0110] Get 100g of pseudo-boehmite SB powder produced by Sasol Company, add 3.0g of hydroxyethyl methylcellulose, 2g of hydroxypropylmethylcellulose, 3.0g of turnip powder and 90mL of deionized water, fully stir and mix, After being uniformly kneaded by an extruder, the extruded bar is formed to obtain a shaped bar. The aluminum hydroxide shaped strips were placed in an oven at 250° C. and dried for 4 hours to obtain the hydrated alumina shaped carrier S2. The radial crushing strength, water absorption rate and δ value of the molded carrier S2 after drying were measured, and the results are listed in Table 1.

Embodiment 3

[0120] Add 50 grams of ammonium molybdate to 120 milliliters of water, add ammonia water with a concentration of 25% dropwise under heating and stirring until the ammonium molybdate is dissolved, then add 30 grams of cobalt nitrate and 10 grams of ammonium fluoride, stir and dissolve, then add 20 milliliters of ethanol , and then add water to make up to 200 ml. 100 g of support S1 were impregnated with the above aqueous solution by the excess impregnation method (ratio of impregnating liquid by volume to support by weight in the impregnation mixture: 2.0) for 0.1 hour. The impregnated mixture was placed in a high-pressure reactor for hydrothermal treatment. The conditions of the hydrothermal treatment included: the temperature was 150°C, the time was 4 hours; the pressure was 0.7MPa, wherein, P 0 =0.5MPa, ΔP=0.2MPa. The mixture obtained by hydrothermal treatment was cooled to room temperature, and after filtration, the obtained solid was dried at 120° C. for 2 hours, and then...

Abstract

A hydrogenation catalyst and preparation and application thereof. The catalyst comprises at least one VIII-group metal component and at least one VIB-group metal component introduced on a molded carrier containing water and alumina, wherein the method for introducing at least one VIII-group metal component and at least one VIB-group metal component on the molded carrier containing water and alumina comprises the following steps: (1) dipping the molded carrier containing water and alumina with an aqueous solution which contains at least one compound containing VIB-group metal elements, and at least one compound containing VIII-group metal elements, and contains or does not contain a cosolvent to obtain a dipping mixture; (2) performing hydro-thermal treatment of the dipping mixture obtained in step (1) in a closed reactor, wherein the hydro-thermal treatment is carried out at a pressure of P0+[delta]P, and [delta]P is 0.05-15 MPa; and (3) performing solid-liquid separation of the mixture obtained by the hydro-thermal treatment, and drying the obtained solid. When the catalyst prepared by the method is used in hydrocarbon oil hydrorefining, the performance is improved.

Description

technical field [0001] The invention relates to a hydrogenation catalyst and a method for preparing the catalyst; the invention also relates to a hydrocarbon oil hydrofinishing method using the catalyst. Background technique [0002] With the increasingly stringent environmental protection requirements worldwide, countries have increasingly stringent requirements on the quality of vehicle fuel. In addition, due to the reduction of oil resources, the nature of crude oil has become heavier and worse, and refineries have to process lower-quality crude oil. Therefore, greatly reducing the content of impurities and polycyclic aromatic hydrocarbons in diesel oil and significantly improving the quality of diesel oil has become an urgent problem for oil refining companies to solve. Hydrogenation technology is one of the main technologies to reduce the impurity content in oil and improve the quality of oil, and its core is hydrogenation catalyst. [0003] Therefore, the development...
