The effects of preparation method of atmospheric residue hydrodesulfurization catalyst on the physical and chemical properties of support and pore structure on the catalytic performance were investigated. The experimental results show that the carrier prepared by the optimized method has the advantages of large pore volume, large specific surface area and concentrated pore distribution The introduction of additives significantly improved the catalytic performance of the catalyst; when the pore distribution is mainly concentrated in the 5 ~ 10nm catalyst for atmospheric residue hydrodesulfurization is appropriate. The small test-type catalyst (FZC 30 1) was tested on a 200-mL hydrogenation unit for 200 h. The results showed that the reaction performance of the FZC 30 1 catalyst in the treatment of the middle-high-sulfur atmospheric residue in the Middle East Better than similar foreign catalyst level, and has good activity stability. The industrial trial production of FZC 30 1 catalyst repeated the small test results, laying the foundation for industrial applications.
