Problems solved by technology

Residual oil contains a large amount of metal impurities such as Ni, V, Fe, Ca and solid impurities. If these impurities cannot be effectively removed, it will have an adverse effect on the downstream hydrogenation catalyst and easily deactivate the downstream catalyst.

Embodiment 1

[0035] Example 1 illustrates the macroporous alumina carrier used in the catalyst provided by the present invention and its preparation method.

[0036] Example 1

[0037] Take by weighing the dry rubber powder (dry basis is 73% that Changling Refinery Catalyst Factory produces, and wherein pseudo-boehmite content is 68%, and gibbsite content is 5 weight %, and surplus is amorphous alumina) 1000 gram, 36 grams of fennel powder (product of Henan Lankao Tianjing Rubber Factory), 25g hydroxymethyl cellulose are mixed homogeneously. Take 12g of titanium tetrachloride and dissolve it with 1000mL deionized water to form a salt solution; take 20mL of nitric acid and add 200mL of deionized water to prepare a dilute acid solution; Aluminum stone powder, kneading for 20 minutes. Extrude into a butterfly bar with an outer diameter of φ1.1mm on a twin-screw extruder. The wet strip was dried at 120°C for 4 hours and calcined at 880°C for 4 hours to obtain carrier Z1. The physical and c...

Embodiment 2

[0042] Get the carrier Z1200 grams that embodiment 1 prepares, use 500 milliliters to contain V 2 o 5 50 g / L, NiO14 g / L mixed solution of ammonium metavanadate and nickel nitrate was impregnated for 1 hour, filtered, dried at 120°C for 4 hours, and calcined at 400°C for 3 hours to obtain protective agent C1. The composition of protective agent C1 is listed in Table 2.

Embodiment 3

[0046] Get the carrier Z1200 grams that embodiment 1 prepares, use 500 milliliters to contain V 2 o 5 18 g / L, NiO 29 g / L mixed solution of ammonium metavanadate and nickel nitrate was impregnated for 1 hour, filtered, dried at 120°C for 4 hours, and calcined at 400°C for 3 hours to obtain protective agent C2. The composition of protectant C2 is listed in Table 2.

Abstract

The invention relates to a hydrogenated active protective agent taking alumina containing IVB group metal as a carrier, as well as the preparation and the application of the hydrogenated active protective agent. The hydrogenated active protective agent comprises an alumina carrier containing IVB group metal and hydrogenated active metallic component loaded on the carrier, and is characterized in that the hydrogenated active metallic component is at least one metallic component chosen from VIII group and at least one metallic component combination chosen from VB group, in percentage by weight, the content of the VIII group metallic component is 0.2 to 15%, and the content of the VB group metallic component is also 0.2 to 15% on basis of oxide and by taking the protective agent as standard. Compared with the hydrogenated protective agent provided in the prior art, the hydrogenated active protective agent provided by the invention has good hydrodemetallization activity.

Description

technical field [0001] The invention relates to a hydrogenation active protective agent, its preparation and application. 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 metal impurities such as Ni, V, Fe, Ca and solid impurities. If these impurities cannot be effectively removed,...
