Embodiment 1

[0064] 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

[0066] 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

[0068] 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 method for improving properties of heavy oil hydrogenation products includes the steps of: under hydrotreating reaction conditions, contacting the residual oil feedstock with a catalyst composition containing by volume 5-60% of a hydrotreating catalyst I, 5-50% of a hydrotreating catalyst II and 10-60% of a hydrotreating catalyst III. The hydrotreating catalyst I contains a molding alumina carrier, at least one IV B hydrogenation active metal component and at least one VB hydrogenation active metal component, and characterized by the mercury injection method, the carrier has pore volume of 0.95-1.2 ml / g and specific surface area of 50-300 m<2> / g, and the carrier is in doublet pore distribution in the diameters of 10-30 nm and 300-500 nm, wherein pores with diameter of 10-30nm account for 55-80% of the total pore volume and pores with diameter of 300-500 nm account for 10-35% of the total pore volume. Compared with the prior art, the invention has better residual oil hydrotreatment performance.

Description

technical field [0001] The invention relates to a method for hydrotreating hydrocarbon oil. Background technique [0002] With the intensified trend of heavy crude oil and the increasing demand for light oil products in social development, the combined process technology of heavy oil hydrogenation and catalytic cracking is generally favored by oil refining companies. The combined process can not only increase the yield of light oil, but also help reduce the emission of sulfur, nitrogen and other pollutants, and has obvious social and economic benefits. Affected by the catalytic cracking process and catalyst, in order to increase the yield of light oil products and reduce the unit consumption of the catalyst, it is required that the metal Ni+V content in the heavy oil catalytic cracking raw oil should be less than 20ppm, the sulfur content should be less than 0.5%, and the residual carbon content should be less than 6.0%. However, due to the continuous deterioration of raw ...
