Embodiment 1

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

Embodiment 2

[0025] After mixing 40.00g 80-mesh bauxite powder and 8.00g 80-mesh cobalt-containing molybdenum waste catalyst powder, use a vulcanizing agent to vulcanize, and the vulcanizing agent is carbon disulfide, and then dry-mix with 20.57g nano-zinc oxide powder, stir well, and mix Catalyst 2 was obtained after homogenization.

Embodiment 3

[0027] 40.00g of bauxite powder and 8.00g of cobalt-containing molybdenum waste 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 are dry mixed, fully stirred, and the catalyst 3 is obtained after mixing uniformly.

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 technical field of petrochemical industry, 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 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 and operating costs. It...
