Research on pilot test of hydrogenation of slurry bed in Yulin

以榆林减渣为原料,在浆态床加氢裂化装置进行中试试验。实验结果表明,在反应温度465℃、反应压力20 MPa、空速0.5 h-1、氢油比2 000 L/kg的条件下,榆林减渣加氢裂化反应性能和产物分布更优,>525℃的重组分和沥青质的转化率分别为84.69%和86.03%,气体产率和液收分别为7.57%和83.74%;采用Fe系催化剂等量替换赤泥催化剂,在抑制气体生成的同时提高了>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%。

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 C,reaction pressure 20 MPa,space velocity 0.5 h-,and hydrogen oil ratio 2,o00 L/kg,the hydrocracking reaction performance and product distribution of Yulin residue were better.The conversion rates of>525 C 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 C macromolecules,asphaltenes,and liquid yield were increased by 2.32%,2.67%,and2.02%,respectively.
