摘要: 采用二次纳米自组装方法制备出具有大孔道的催化剂0 1 0 6、 1 2 2 7, 两种纳米自组装催化剂在3 0~1 0 0n m孔径分布分别占1 1%、 2 8%。纳米自组装催化剂具有低堆积密度和高金属含量等特点。在1 0mL固定床微型反应器中, 以镇海炼化的催化裂化柴油为原料, 在温度3 6 0曟、 压力7MP a、 氢油体积比为6 0 0暶1、 体积空速为1. 5h-1条件下, 考察了两种纳米自组装催化剂的初活性评价, 并与现有工业催化剂作对比。结果表明, 两种纳米自组装催化剂0 1 0 6、 1 2 2 7可使催化裂化柴油的含硫质量分数从1 24 0 0毺 g / g分别最低降到4 8 3、 2 8 3毺 g / g, 最高脱硫率分别为9 6. 1 0%、 9 7. 7 1%; 将含氮质量分数从15 0 7毺 g / g分别最低降到3 5. 7、 1 4. 0毺 g / g, 最高脱氮率分别为9 7. 6 3%和9 9 灡 0 0%; 其最高芳烃饱和率分别为6 7. 9 9%和6 8. 8 8%; 而 参比催化剂仅可使催化裂化柴油的含硫质量分数从1 24 0 0毺 g / g最低降到5 3 7毺 g / g, 最高脱硫率为9 4. 5 7%; 将含氮质量分数从15 0 7毺 g / g最低降到6 4. 6毺 g / g, 最高脱氮率为9 5. 5 4%; 其最高芳烃饱和率为6 5. 6 5%。

Abstract: Adopting secondary nano selfassembly method to prepare macroporous catalyst(0106,1227)with small stacking density and high metal loading, the distribution of pore volume centralized from 30 nm to 100 nm,which accounts for 11%,28%. The first activity of two kinds of nano selfassembly catalyst(0106,1227) was investigated with Zhenhai FCC diesel oil as feed at reaction temperatures of 360 ℃,reaction pressure of 7 MPa,hydrogenoil volume ratio of 600,volume space velocity oh 1.5 h-1 in a fixed bed micro reactor of 10 mL,and with reference agent as a contrast. The experimental results show that the two kinds of nano selfassembly catalyst (0106,1227)has higher activity of hydrodesulfurization,hydrodenitrificationand aromatics saturation than the reference catalyst.The sulfur mass fraction of FCC diesel [KG*4]oil[KG*4] feedstock [KG*4]could [KG*4]be [KG*4]reduced from 12 400 μg/g to 483,283 μg/g which the highest desulfurization rate of 96.10% and 9771%;the nitrogen mass fraction of FCC diesel oil feedstock could be reduced from 1 507 μg/g to 35.7,14 μg/g which the highest denitrification rate of 9763% and 9900%; the highest aromatics saturation rate of 67.99% and 68.88%,while only to 537,64.6 μg/g and 9457%,95.54%,6565% over the reference catalyst.
