Embodiment 1

[0065] Weigh 1000 grams of PA-1, then add 1000 milliliters of an aqueous solution containing 10 milliliters 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 PC-A1 of PA-1. See Table 1 for the k value of PC-A1.

Embodiment 2

[0067] Weigh 1000 grams of PA-1, then add 1000 milliliters of an aqueous solution containing 10 milliliters of nitric acid (product of Tianjin Chemical Reagent No. The wet strips were dried at 120°C for 4 hours, and roasted at 800°C for 4 hours to obtain the carrier. The carrier strips were shaped and sieved, and the carrier strip materials (generally called industrial carrier waste) with a length of less than 2mm were ground, sieved, and collected. Among them, sieve with 100-200 meshes to obtain the modified product PC-A2 of PA-1. See Table 1 for the k value of PC-A2.

Embodiment 3

[0069] Weigh 1000g of PA-2, and flash dry at 400°C for 6 minutes to obtain PC-A3, a modified product of PA-2. See Table 1 for the k value of PC-A3.

Abstract

A hydrogenation-activity-protected catalyst, preparation thereof and applications of the catalyst are disclosed. The catalyst comprises a carrier and hydrogenation active metal components loaded by the carrier, wherein the carrier comprises aluminum oxide and boron. By representation by a mercury intrusion method, the pore volume of the carrier is 0.6-1.4 mL / g, the specific surface area is 80-400 m<2> / g, the carrier is distributed in a double peak pore manner at a diameter of 5-20 nm and a diameter of 100-300 nm, the pore volume of pores having a diameter of 5-20 nm is 30-60% of the total pore volume, and the pore volume of pores having a diameter of 100-300 nm is 15-45% of the total pore volume. The hydrogenation active metal components are selected from at least one metal component of the VIII group and at least one metal component of the VB group. Based on the catalyst and calculated in an oxide form, the content of the metal component of the VIII group is more than 0 and not more than 0.8% by weight, and the content of the metal component of the VB group is more than 0 and not more than 5% by weight. Compared with the prior art, the catalyst has good hydrogenation demetallation activity.

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...
