| 摘要: |
| 以硅胶为载体,利用等体积浸渍法负载3种不同杂多酸制备一种吸附剂,以喹啉的十二烷溶液为模拟油,考察酸负载量、反应时间、反应温度、剂油质量比对油品脱氮率的影响。结果 表明,在酸负载量为40%(w),反应温度为50 ℃,反应时间为45 min,剂油质量比为1∶5的条件下,吸附剂可有效吸附脱除模拟油中的氮化物,脱氮率达到90%以上。采用傅里叶红外光谱(FT-IR)对吸附剂的物化性质进行了表征。 |

| Abstract: |
| Using silica gel as a carrier, three different kinds of heteropolyacids were loaded to prepare a kind of adsorbent by equal volume impregnation method. Using the mixed solution of quinoline and dodecane as simulated oil, the influence of heteropolyacid loading, reaction time, reaction temperature, and mass ratio of adsorbent to oil on denitrification rate of oil were studied. The results showed that under the conditions of the acid loading of 40%, the reaction temperature of 50 ℃, the reaction time of 45 minutes, and the mass ratio of adsorbent to oil of 1∶5, the nitride in the oil can be effectively removed with the presence of adsorbent, and the denitrification rate of oil is more than 90%. The physical and chemical properties of the adsorbent were characterized by FT-IR. |
