Embodiment 1

[0032] After mixing 35.00g of kaolin powder and 33.00g of iron-containing ore (both of 90 mesh), vulcanize with a vulcanizing agent. The vulcanizing agent is carbon disulfide, and then dry blend with 32.00g of 90 mesh of zinc oxide powder, fully stir and mix After homogenization, catalyst 1 was obtained.

Embodiment 2

[0034] Under stirring conditions, add 0.25mol La(NO 3 ) 3 Dissolve in 100mL water, add citric acid and stir to dissolve; then add 0.5mol Fe(NO 3 ) 3 , And then add 18g of sodium polyacrylate, continue to stir for 30min to obtain the reaction liquid, and obtain the micro mesoporous lanthanum ferrite after roasting and grinding.

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

Embodiment 3

[0037] After calcining the kaolin powder and iron-containing ore powder at 450°C, mix 20.00g of kaolin powder and 55.00g of iron-containing ore (both 80 mesh) uniformly, and then vulcanize with a vulcanizing agent. The vulcanizing agent is carbon disulfide, 25.00g Zinc oxide powder with zinc-aluminum spinel structure is mixed with 5g waste ZSM-5, and then dry-mixed with 7g vulcanized micro-mesoporous lanthanum ferrite powder, and then mixed with kaolin powder and iron-containing ore mixture. , Get 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 a low-quality heavy oil suspended bed hydrocracking catalyst and a preparation method. Background technique [0002] Inferior heavy oil is a general term for a class of difficult-to-volatile and difficult-to-handle high-viscosity substances, mainly including: residual oil, shale oil, oil sands oil, heavy (heavy) oil, super heavy oil, deep petroleum, asphalt, coal tar, etc. The main characteristics of inferior heavy oil are its high sulfur, high residual carbon, high nitrogen and high metal content, and its huge output, high processability, but difficult processing. [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 deep processing method for low-quality heavy oil with low i...
