Embodiment 1

[0024] The commercially available pseudo-boehmite dry rubber powder (with a water content of 25% by weight) is calcined at 800° C. for 2 hours to obtain alumina powder. Weigh 38 grams of alumina powder, then weigh 113 grams of pseudo-boehmite dry rubber powder, 9.3 grams of carbon black, 3.4 grams of squeezing aid sesame powder, and 150 mL of active metal salt solution. The solution contains 2 g / 100 mL of Polyethylene glycol 400. The above materials are mixed uniformly to form a plastic body, and then extruded into a cylindrical bar on an extruder, dried at 110°C for 2 hours, and then calcined at 650°C for 3 hours to obtain catalyst A. Among them, the active metal salt solution contains ammonium molybdate and basic nickel carbonate, and the content is in accordance with MoO 3 Calculated as 10wt%, and as NiO 2wt%.

Abstract

The invention discloses a heavy oil hydrotreating catalyst and a preparation method thereof. The method for preparing the catalyst adopts a complete mixed kneading method; a carrier material comprises pseudo-boehmite glue powder and alumina powder; and an active metallic solution contains nonionic surfactant. The catalyst prepared by the method has the characteristics of large pore volume and pore diameter, proper specific surface area, even active metal dispersion and the like, and can be used in the processes of heavy oil hydrodemetalization, hydrodesulfurization and the like.

Description

Technical field [0001] The invention relates to a hydrogenation treatment catalyst and a preparation method thereof, in particular to a heavy oil and residual oil hydrodemetalization or desulfurization catalyst and a preparation method thereof. Background technique [0002] Residue oil generally contains a large amount of heavy metals such as nickel, vanadium, etc. During the hydroprocessing of the residue oil, they accumulate on the catalyst, causing the catalyst to deactivate, and the deactivated catalyst is difficult to regenerate. In addition, due to the high viscosity of residual oil and a large amount of impurities such as S and N, the space velocity of the residual oil hydrotreating process is very small, so the amount of catalyst is greatly increased compared with other refining processes. The major factor that determines the technical and economic feasibility of the process is how to reduce the cost of the catalyst so that the entire hydroprocessing process is more techn...
