Embodiment 1

[0027] After mixing 45.00g of kaolin and 5.00g of ammonium molybdate (both 50 mesh) evenly, vulcanize with a vulcanizing agent, the vulcanizing agent is carbon disulfide, and then dry mix with 50.00g of zinc oxide powder of 50 mesh, fully stir, and mix evenly Catalyst 1 is obtained.

Embodiment 2

[0029] Under stirring conditions, 0.25mol La(NO 3 ) 3 Dissolve in 100mL water, add citric acid and stir to dissolve; then add 0.5 mol Fe(NO 3 ) 3 , and then add 18g of sodium polyacrylate, and continue to stir for 30 minutes to obtain a reaction solution, which is roasted and ground to obtain micro-mesoporous lanthanum ferrite.

[0030] After roasting kaolin and zinc oxide at 450°C, mix 35.00g of kaolin with 10.00g of ammonium molybdate (both 80 meshes) and 2.00g of micro-mesoporous lanthanum ferrite powder, and then vulcanize with a vulcanizing agent. The vulcanizing agent is The sulfur powder was then dry-mixed with 53.00 g of nano-zinc oxide powder of 50 meshes, fully stirred, and evenly mixed to obtain Catalyst 2.

Embodiment 3

[0032] Mix 42.00g of kaolin with 8.00g of ammonium molybdate (both 70 meshes) and 6.00g of micro-mesoporous lanthanum ferrite powder, then vulcanize with a vulcanizing agent, which is carbon disulfide, and then mix with 44.00g of 50 meshes containing zinc The zinc oxide powder with aluminum spinel structure is dry mixed, fully stirred, and the catalyst 3 is obtained after uniform mixing.

Abstract

The invention discloses a heavy oil suspended bed hydro-cracking catalyst. The catalyst comprises 15.0-55.0 percent by weight of vulcanized kaolin powder, 10.0-65.0 percent by weight of zinc oxide powder and 1.0-25.0 percent by weight of vulcanized molybdenum-containing compound powder; and the catalyst can be prepared by dry-blending the vulcanized kaolin powder, the vulcanized molybdenum-containing compound powder and the zinc oxide powder. In addition, the catalyst disclosed by the invention can also comprise vulcanized lanthanum ferrite. The prepared catalyst is used for the suspended bedhydro-cracking reaction of inferior heavy oil, is low in coke yield, high in liquid yield and desulfurization rate and strong in resistance to sulfur, colloids and other impurities.

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 suspension bed hydrocracking catalyst for low-quality heavy oil and residual oil and a preparation method thereof. Background technique [0002] Inferior heavy oil is a general term for a class of difficult-to-volatilize and difficult-to-handle high-viscosity substances, mainly including: residual oil, shale oil, oil sand oil, heavy (thick) oil, super-heavy oil, deep oil, asphalt, coal tar, etc. The main characteristics of low-quality heavy oil are its high sulfur, high carbon residue, high nitrogen and high metal content, and it has a huge output and high processability, but the processing is difficult. [0003] The suspended bed hydrogenation process passes highly dispersed fine particle catalysts or additives together with feedstock oil and hydrogen through the reactor. It is a deep processing m...
