Embodiment 1

[0046] The pseudo-boehmite dry rubber powder RPB90 produced by 1 kilogram of Changling Catalyst Factory and 30 grams of turnip powder and 25 grams of titanium dioxide are mixed uniformly, and at room temperature, the mixture is mixed with 20 milliliters of nitric acid (65% by mass fraction) 1.1 liters of the aqueous solution was mixed evenly, and after being kneaded into a plastic body on a twin-screw extruder, extruded into a trilobal strip of ф1.1 mm, the wet strip was dried at 120°C for 3 hours, and then roasted at 600°C for 3 hours to obtain Titanium shaped alumina support Z1. The physical and chemical results of the determination of Z1 are shown in Table 1.

Embodiment 2

[0048] The pseudo-boehmite dry rubber powder RPB100 produced by 1 kilogram of Changling Catalyst Factory is mixed with 30 grams of turnip powder and 40 grams of titanium dioxide. Mix 1.2 liters of aqueous solution evenly, continue kneading on a twin-screw extruder to form a plastic body, and then extrude it into a butterfly-shaped strip of ф1.1mm. After the wet strip is dried at 110°C for 2 hours, it is roasted at 700°C for 3 hours to obtain a titanium-containing molding. Alumina support Z2. The physical and chemical results of the determination of Z2 are shown in Table 1.

Embodiment 3

[0051] Weigh 150g of the Z1 carrier and place it in the hydration kettle, add 450g of deionized water, seal the hydration kettle and put it in the oven, heat it with a programmed temperature rise, and control the heating rate to 10°C·min -1 , the treatment temperature is 80° C., and the treatment time is 12 hours. After the completion of the hydrothermal treatment, the alumina was filtered, and then dried at 120° C. for 3 hours to obtain a hydrothermally treated alumina carrier.

[0052] Take 100 grams of carrier Z1 after heat treatment in water, and use 220 milliliters of MoO 3 170 g / L, NiO 30 g / L mixed solution of ammonium molybdate and nickel nitrate was impregnated for 1 hour, filtered, dried at 120°C for 2 hours, and calcined at 410°C for 4 hours to obtain catalyst C1. Calculated by oxide and based on the load on the surface of the unit carrier, the content of molybdenum oxide and nickel oxide in catalyst C1 is measured by X-ray fluorescence spectrometer, and whether mol...

Abstract

The invention provides a heavy oil hydrogenation catalyst. The catalyst comprises a titanium-containing molded alumina carrier, a metal component molybdenum and a metal component cobalt or nickel; the content of titanium (by oxide) in the titanium-containing molded alumina carrier used as a reference is 0.5-8wt%; the content of the metal component molybdenum (by oxide) in the catalyst with the unit carrier surface load as a reference is 4.8-9.0[mu]mol/m<2>, and the content of the metal component cobalt or nickel (by oxide) is 1.5-4.0[mu]mol/m<2>; and no MoO3 characteristic peak appears at a diffraction angle 2theta of 24-28DEG in the XRD characterization map of the catalyst. Compared with heavy oil hydrogenation catalysts, the heavy oil hydrogenation catalyst provided by the invention has better hydrodesulfurization, nitrogen removal and residual carbon removal effects in the heavy metal hydrogenation process.

Description

technical field [0001] The invention relates to a heavy oil hydrogenation treatment catalyst and a heavy oil hydrogenation treatment method using the heavy oil hydrogenation treatment catalyst. Background technique [0002] Heavy oil processing, especially the deep processing of residual oil, not only helps to improve the utilization rate of crude oil, alleviate the tense trend of energy supply, but also reduce environmental pollution and realize efficient and clean utilization of energy. [0003] Heavy oil is enriched with impurities such as sulfur, nitrogen, metals, and carbon residues in crude oil. These impurities have serious adverse effects on subsequent processing and product properties, so they must be removed. Since impurities such as sulfur and nitrogen in heavy oil are mostly enriched in macromolecular polycyclic aromatic hydrocarbons, it is difficult to remove them. Therefore, catalysts for related reactions such as desulfurization, denitrogenation, and carbon re...
