Embodiment 1

[0100] Take carrier Z1200g, use 500ml containing V 2 o 5 50 grams per liter, NiO14 grams per liter of ammonium metavanadate and nickel nitrate mixed solution with 20 milliliters of ethanol, after stirring and dissolving, adopt the excess impregnation method to impregnate the carrier with the above-mentioned aqueous solution (the impregnating solution by volume in the impregnating mixture is equal to The ratio of the carrier by weight is: 2.6), and the impregnation time is 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 calcined at 450° C. for 3 hours to obtain the protective agent C1. The composition of ...

Embodiment 2

[0106] Take carrier Z1200g, use 500ml containing V 2 o 5 18 grams per liter, NiO24 grams per liter of ammonium metavanadate and nickel nitrate are mixed with 15 milliliters of isopropanol and stirred evenly, and the method of excessive impregnation is used to impregnate the carrier with the above-mentioned aqueous solution (the impregnating liquid in the impregnating mixture and The ratio of the carrier by weight is: 2.6), and the impregnation time is 0.2 hours. The impregnated mixture is placed in a high-pressure reactor for hydrothermal treatment. The conditions of hydrothermal treatment include: temperature is 200°C; time is 10 hours; pressure is 2.1MPa, wherein, P 0 =1.5MPa, ΔP=0.6MPa. 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 to obtain protective agent C2. The composition of protective agent C2 is listed in Table 1.

Embodiment 3

[0108] Take carrier Z1200g, use 500ml containing V 2 o 5 70 grams per liter, the mixed solution of ammonium metavanadate and nickel nitrate of NiO8 grams per liter, adopt the method for excessive impregnation to impregnate the carrier with the above-mentioned aqueous solution (the ratio of the impregnating solution by volume and the carrier by weight in the impregnated mixture is : 2.5), the immersion time is 0.5 hours. The mixture obtained by impregnation is placed in a high-pressure reactor for hydrothermal treatment. The conditions of the hydrothermal treatment include: the temperature is 100 ° C; the time is 24 hours; nitrogen is introduced into the high-pressure reactor during the hydrothermal treatment to make the pressure in the high-pressure reactor is 5.2MPa, where P 0 =0.2MPa, ΔP=5.0MPa. 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 dried at 400° C....

Abstract

A hydrogenation protection catalyst and its preparation and application, comprising introducing at least one metal component of Group VB and at least one metal component of Group VIII on a shaped porous carrier, wherein at least one metal component of Group VIII is introduced on a shaped porous carrier A method for a Group VB metal component and at least one Group VIII metal component comprises the steps of: (1) using a compound containing at least one Group VIII metal element and at least one Group VB metal element The compound and the aqueous solution containing or not containing co-solvent impregnate the shaped porous carrier to obtain an impregnation mixture; (2) The impregnation mixture obtained in step (1) is subjected to hydrothermal treatment in a closed reactor, and the hydrothermal treatment at pressure P 0 It is carried out under the condition of +ΔP, and ΔP is 0.05-15 MPa; and (3) the mixture obtained by hydrothermal treatment is subjected to solid-liquid separation, and the obtained solid phase is dried. When the catalyst prepared by the method provided by the invention is used in heavy oil hydrotreating, its performance is improved.

Description

technical field [0001] The invention relates to a hydrogenation protection catalyst and a method for preparing the catalyst; the invention also relates to a heavy oil hydrotreating method using the hydrogenation protection catalyst. Background technique [0002] As crude oil becomes heavier and inferior, the difficulty of crude oil processing increases, and the yield of light oil products decreases. However, the market demand for high-quality light oil products continues to increase, and environmental protection regulations are becoming more and more inclusive. strict. At present, the processing and full utilization of heavy oil, especially residual oil, is becoming a major topic of concern in the global oil refining industry, and residual oil hydrogenation technology is a widely used processing technology in heavy oil processing technology, and is recognized as an economical and environmentally friendly deep processing technology . Residual oil contains a large amount of ...
