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

[0032] Example 1 illustrates the alumina carrier used in the catalyst provided by the present invention and its preparation method.

[0033] Example 1

[0034] 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,, 30 gram turmeric powder (Henan Lankao turmeric glue factory product), 30g hydroxymethyl cellulose mixes, add the aqueous solution 1200 milliliters that contains nitric acid 16g afterwards, extrude into outer diameter 2.5mm on the plunger type extrusion machine, Raschig ring bar with inner diameter of 1.0mm. The wet strip was dried at 120°C for 4 hours and calcined at 960°C for 3 hours to obtain carrier Z1. The pore volume of carrier Z1 is 0.73mL / g, and the specific surface area is 118m 2 / g.

Embodiment 2

[0037] 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 CZ1. The composition of protective agent CZ1 is listed in Table 1.

Embodiment 3

[0041] Get the carrier Z1200 grams that embodiment 1 prepares, use 500 milliliters to contain V 2 o 5 18 g / L, NiO 24 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 protective agent C2 is listed in Table 1.

Abstract

The invention discloses a hydrogenation active protective agent with aluminum oxide as a carrier and preparation as well as application thereof. The protective agent contains the aluminum oxide carrier and a hydrogenation active metal component loaded on the carrier, and is characterized in that the hydrogenation active metal component is combination of at least one metal component selected from VIII group and at least one metal component selected from VB group; and in terms of oxide and based on the protective agent, the content of the VIII group metal component is 0.5-15 percent by weight and the content of the VB group metal component is 0.5-15 percent by weight. Compared with the hydrogenation protective agent provided by the prior art, the hydrogenation protective agent provided by the invention has the advantage of better hydrodemetalization activity.

Description

technical field [0001] The invention relates to a hydrogen activity protecting 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, it...
