Embodiment 1

[0032] Mix 35.00g of kaolin powder and 33.00g of iron-containing ore (both 90 mesh) evenly, then use a vulcanizing agent for vulcanization. The vulcanizing agent is carbon disulfide, and then dry-mix with 32.00g of 90-mesh zinc oxide powder, stir well, and mix Catalyst 1 was obtained after homogenization.

Embodiment 2

[0034] Under stirring conditions, 0.25mol La (NO 3 ) 3 Dissolve in 100 mL of water, add citric acid and stir to dissolve; then add 0.5 mol Fe(NO) 3 ) 3 , and then add 18 g of sodium polyacrylate, continue to stir for 30 minutes to obtain a reaction solution, which is calcined and ground to obtain micro-mesoporous lanthanum ferrite.

[0035] After roasting kaolin powder and iron-containing ore powder at 430℃, mix 40.00g kaolin powder and 30.00g iron-containing ore (both 60 mesh) evenly, and then use vulcanizing agent for vulcanization treatment. The vulcanizing agent is sulfur powder, 5g After vulcanization, the micro-mesoporous lanthanum ferrite powder was dry-mixed with 30.00 g of zinc oxide powder containing zinc-aluminum spinel structure, and then mixed with kaolin powder and iron-containing ore powder, fully stirred, and mixed uniformly to obtain catalyst 2.

Embodiment 3

[0037] After roasting kaolin powder and iron-containing ore powder at 450℃, mix 20.00g kaolin powder and 55.00g iron-containing ore (both 80 mesh) evenly, and then use vulcanizing agent for vulcanization treatment. The vulcanizing agent is carbon disulfide, 25.00g Zinc oxide powder containing zinc-aluminum spinel structure was mixed with 5g of waste ZSM-5, and then dry-mixed with 7g of vulcanized micro-mesoporous lanthanum ferrite powder, mixed uniformly, and then mixed with kaolin powder and iron-containing ore mixture uniformly , to obtain catalyst 3.

Abstract

The invention discloses a suspended bed hydrocracking catalyst for inferior heavy oil and a preparation method of the catalyst. The catalyst comprises zinc oxide powder, vulcanized kaolin powder and vulcanized iron-containing ore powder, wherein the content of the vulcanized kaolin powder is 15.0-60.0 wt%, the content of the vulcanized iron-containing ore powder is 15.0-55.0 wt%, the content of zinc oxide powder is 15.0-50.0 wt%, and the kaolin powder, the iron-containing ore powder and the zinc oxide are mixed dryly. The catalyst has low coke rate, high desulfurization rate, strong resistanceto impurities such as sulfur, metal, nitrogen, carbon residues and the like, and is used for the suspended bed hydrocracking reaction of the inferior heavy oil.

Description

technical field [0001] The invention belongs to the technical field of petrochemical industry, and relates to a hydrogenation catalyst and a preparation method, in particular to an inferior heavy oil suspended bed hydrocracking catalyst and a preparation method. Background technique [0002] Inferior heavy oil is a general term for a class of non-volatile and intractable high-viscosity substances, mainly including: residual oil, shale oil, oil sand oil, heavy (heavy) oil, super heavy oil, deep oil, asphalt, coal tar and so on. The main characteristics of inferior heavy oil are its high sulfur, high carbon residue, high nitrogen and high metal content, and its huge output and high processability, but it is difficult to process. [0003] The suspended bed hydrogenation process passes the highly dispersed fine particle catalyst or additives together with the feedstock oil and hydrogen through the reactor. It is a low-quality heavy oil deep processing method with low investment ...
