时提高了>525 ℃重组分、沥青质转化率及液体收率，分别提高了2.32%、2.67% 和2.02%。
Abstract：Using Yulin residue as the raw material, a pilot test was conducted in a slurry bed hydrocracking unit. The experimental
results showed that under the conditions of reaction temperature 465 ℃, reaction pressure 20 MPa, space velocity 0.5 h-1, and
hydrogen oil ratio 2,000 L/kg, the hydrocracking reaction performance and product distribution of Yulin residue were better. The
conversion rates of >525 ℃ macromolecules and asphaltenes were 84.69% and 86.03%, respectively, and the gas yield and liquid
yield were 7.57% and 83.74%. By replacing the red mud catalyst with a Fe-based catalyst in the same amount, the gas generation
was inhibited while the conversion rates of >525 ℃ macromolecules, asphaltenes, and liquid yield were increased by 2.32%, 2.67%,
and 2.02%, respectively.
