Abstract
A catalyst for residue suspended bed hydrocracking and a preparation method and application thereof are disclosed. The catalyst is obtained by mixing a VIIB or VIIIB group transition metal salt solution with a ferric salt solution, conducting parallel-flow precipitation with an alkaline solution, adding a silicon source, and then conducting aging, washing, drying, and calcination. The catalyst has a stable structure and excellent hydrogenation activity. When used in a residue suspended bed hydrocracking reaction, the yield of liquid is up to 91 wt %, the yield of gasoline and diesel oil is up to 60 wt %, and both the yield of gas and the yield of coke are low. The catalyst has a good application prospect in residue suspended bed hydroconversion process.
