Embodiment 1

[0061] Weigh 1000 g of P1-1, then add 1440 ml of aqueous solution containing 10 ml of nitric acid (product of Tianjin Chemical Reagent No. Dry the wet strips at 120°C for 4 hours to obtain dry strips, shape the dry strips, sieve, grind and sieve the dry strip materials (generally called industrial dry strip waste) with a length of less than 2mm, and take 100-200 Mesh sieving to obtain the modified product P2A of P1-1. The k values ​​of P2A are shown in Table 1.

Embodiment 2

[0063] Weigh 1000 g of P1-1, and flash dry at 240°C for 6 minutes to obtain P2B, a modified product of P1-1. See Table 1 for the k values ​​of P2B.

Embodiment 3

[0065] 200 grams each of P2A obtained in Example 1 and P2B obtained in Example 2 were evenly mixed to obtain the modified product P2C of P1-1. See Table 1 for the k value of P2C.

Abstract

A hydrogenation activity protected catalyst and its preparation and application, the hydrogenation activity protection catalyst contains a carrier and a hydrogenation active metal component, wherein the carrier is a bimodal porous alumina containing a Group IVB metal component, Characterized by mercury porosimetry, the carrier has a pore volume of 0.95-1.2 ml / g and a specific surface area of ​​50-300 m 2 / gram, the pore volume of pores with a diameter of 10-30nm accounts for 55-80% of the total pore volume, and the pore volume of pores with a diameter of 300-500nm accounts for 10-35% of the total pore volume. The hydrogenation active metal component is selected From at least one Group VIII metal component and at least one Group VB metal component, the content of the Group VIII metal component is greater than 0 and less than or equal to 0.8% by weight, calculated as oxide and based on the catalyst , the content of the Group VB metal component is greater than 0 to less than or equal to 5% by weight. Compared with the prior art, the hydrogenation activity protected catalyst provided by the invention has better hydrodemetallization activity at the same time.

Description

technical field [0001] The invention relates to a hydrogenation active protection catalyst and 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 re...
