Embodiment 1

[0023] 60.00 g of 60-mesh bauxite powder was vulcanized with a vulcanizing agent, the vulcanizing agent being carbon disulfide, and then dry-mixed with 15.00 g of 80-mesh zinc oxide powder, fully stirred, and evenly mixed to obtain Catalyst 1.

Embodiment 2

[0025] After mixing 40.00g of 80-mesh bauxite powder and 8.00g of 80-mesh cobalt-molybdenum-containing spent catalyst powder, carry out vulcanization treatment with a vulcanizing agent, the vulcanizing agent is carbon disulfide, and then dry-mix with 20.57g of nano-zinc oxide powder, fully stir, and mix Catalyst 2 was obtained after uniformity.

Embodiment 3

[0027] 40.00g of bauxite powder and 8.00g of cobalt-molybdenum-containing spent catalyst powder (both 120 mesh) were vulcanized with a vulcanizing agent. The vulcanizing agent was carbon disulfide, and then mixed with 20.57g of zinc oxide containing zinc-aluminum spinel structure The powders were dry mixed, fully stirred, and evenly mixed to obtain Catalyst 3.

Abstract

The invention discloses a suspended bed hydrocracking catalyst and a preparation method thereof. The suspended bed hydrocracking catalyst comprises a sulfurized bauxite and zinc oxide, wherein the content of the zinc oxide is 1.0-50.0wt%; the suspended bed hydrocracking catalyst can be prepared by dryly mixing the sulfurized bauxite and the zinc oxide. The suspended bed hydrocracking catalyst is high in conversion rate, low in coking rate, high in desulfurization rate and strong in capability of resisting sulfur, metal, nitrogen, residual charcoal and other impurities, and is applied to a suspension bed hydrocracking reaction of poor-quality heavy oil.

Description

technical field [0001] The invention belongs to the field of petrochemical technology, and relates to a hydrogenation catalyst and a preparation method, in particular to a suspended bed hydrocracking catalyst and a preparation method. 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 method for low-quality heavy oil with low investment and oper...
