Embodiment 1

[0102] Take 200g of carrier Z1 and use 500ml of MoO 3 80 g / l, V 2 o 5 16 grams per liter of ammonium heptamolybdate and ammonium metavanadate and 20 milliliters of ethanol mixed solutions, after stirring and dissolving, adopt the excess impregnation method to impregnate the carrier with the above-mentioned aqueous solution (the impregnating liquid in the impregnating mixture and the impregnating liquid by weight The ratio of the carrier 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 hydrodemetallization catalyst C1. The ...

[0108] Take 200g of carrier Z1 and use 500ml of MoO 3 120 g / l, V 2 o 5 The ammonium heptamolybdate and ammonium metavanadate of 50 g / liter are mixed with 15 milliliters of isopropanol and stirred evenly, and the method of adopting excessive impregnation is impregnated carrier with above-mentioned aqueous solution (impregnation solution by volume in the impregnation mixture and by weight The ratio of the carrier 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 hydrodemetallization catalyst C2. The composition of catalyst C2 is listed in Table 1.

Embodiment 3

[0110] Take 200g of carrier Z1 and use 500ml of MoO 3 70 g / l, V 2 o 5 90 g / L mixed solution of ammonium heptamolybdate and ammonium metavanadate, using the method of excess impregnation to impregnate the support with the above aqueous solution (the ratio of the impregnating solution by volume to the support by weight in the impregnation mixture is: 2.5) , The soaking 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 gas is introduced into the high-pressure reactor during the hydrothermal treatment to make the The pressure 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. for 3 hours to obtain hydrodemetallization catalyst...

Abstract

A catalyst with hydrogenation function and its preparation and application, comprising introducing at least one VB group metal component and at least one VIB group metal component on a shaped porous carrier, wherein, on the shaped porous carrier The method for introducing at least one metal component of Group VB and at least one metal component of Group VIB comprises the following steps: (1) using a compound containing at least one metal element containing Group VIB and at least one metal component containing Group VB impregnating the molded porous carrier with a compound of metal elements and an aqueous solution with or without co-solvent to obtain an impregnation mixture; (2) subjecting the impregnation mixture obtained in step (1) to hydrothermal treatment in a closed reactor, the Hydrothermal treatment at pressure P 0 performing under the condition of +ΔP; and (3) performing solid-liquid separation on the mixture obtained by the hydrothermal treatment, and drying the obtained solid phase. 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 catalyst with hydrogenation function and a method for preparing the catalyst; the invention also relates to a heavy oil hydrogenation treatment method using the catalyst. Background technique [0002] As the world-wide contradiction between heavy and low-quality crude oil and diversified and light-weight demand for petrochemical products becomes increasingly acute, the main task of the petrochemical industry will focus on lightening heavy oil. Compared with distillate oil, in addition to impurities such as sulfur and nitrogen, heavy oil also contains a higher proportion of metal impurities such as Ni and V, and has a higher asphaltene content and higher carbon residue value. Among them, if metal impurities such as Ni and V are not effectively removed, they will have an adverse effect on the downstream catalyst, block the pores of the downstream catalyst, and cause the deactivation of the downstream catalyst. Therefore, the d...
