example 1

[0026] Take by weighing 4000 grams of aluminum hydroxide dry rubber powder (product of Changling Refining and Chemical Company Catalyst Factory), extrude into a clover-shaped bar with a circumscribed circle diameter of 1.3 mm, and dry the wet bar at 120° C. for 4 hours, then bake it at 600° C. for 4 hours. Vector S1 is obtained.

[0027] Get 100 grams of carrier S1, impregnate 1 hour with 88 milliliters of aqueous solution containing 6.7 grams of ammonium paramolybdate (chemically pure, Beijing Chemical Plant product), dry at 120° C. for 4 hours, and after being down to room temperature, use nickel nitrate containing (analytical pure, Beijing chemical factory product) 10.5 grams, ammonium metatungstate (industrial grade, product of Sichuan Zigong Cemented Carbide Factory) 27.4 grams of aqueous solution 84 milliliters impregnated for 1 hour, dried at 120 DEG C for 4 hours and roasted at 450 DEG C for 4 hours to obtain catalyst C1 . The composition of catalyst C1 after calcinat...

example 2

[0029] Take 100 grams of the carrier S1 prepared in Example 1, soak it with 88 ml of an aqueous solution containing 6.6 grams of ammonium paramolybdate for 1 hour, dry at 120°C for 4 hours, and after cooling down to room temperature, add 13.0 grams of nickel nitrate and 34.4 grams of ammonium metatungstate 83 ml of aqueous solution was impregnated for 1 hour, dried at 120° C. for 4 hours, and then calcined at 450° C. for 4 hours to obtain catalyst C2. The composition of catalyst C2 after calcination is listed in Table 1.

example 3

[0033] Take 200 grams of the carrier S1 prepared in Example 1, impregnate the carrier with 176 ml of an aqueous solution containing 21.4 grams of ammonium paramolybdate for 1 hour, dry at 120°C for 4 hours, and after cooling down to room temperature, use 71.6 grams of nickel nitrate, metatungstic acid 162 ml of aqueous solution of 129.4 g of ammonium was impregnated for 1 hour, dried at 120° C. for 4 hours, and then calcined at 350° C. for 4 hours to obtain catalyst C3. The composition of catalyst C3 after calcination is listed in Table 1.

Abstract

A hydrocatalyst with high hydrorefining performance contains nickel oxide (1-10 Wt%), molybdenum oxide and tungsten oxide (10-50) and aluminum oxide (rest). It is prepared by introducing Mo, Ni and W to the carrier (aluminum oxide).

Description

technical field [0001] The invention relates to a hydrogenation catalyst and a preparation method thereof. Background technique [0002] Under the hydrogenation reaction conditions, the contact of the hydrocarbon feedstock with the catalyst may occur including: hydrogenation, hydrodesulfurization, hydrodenitrogenation, hydrodemetallization, hydrodearomatization, hydroisomerization, hydrodewaxing, hydrogenation Reactions such as hydrocracking and moderate hydrocracking. The catalysts therein are generally formed by the carrier supporting metal components of Group VIB and Group VIII. The hydrogenation active metal component is usually selected from Co or Ni-Mo or Co or Ni-W, and the carrier is usually selected from alumina, silica-alumina and their modified products. These catalysts can be prepared by impregnating the carrier with an aqueous solution containing the metal compound, and then drying, roasting or not roasting; the carrier, the metal component of Group VIII and t...
