Research on pilot test of hydrogenation of slurry bed in Yulin
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.
