| 摘 要： | 采用一步包覆法成功地将磷钨酸（HPW）固载到多金属有机骨架MIL-101中，将其作为催化剂，氧气（O2）作为氧化剂，用于催化氧化模拟油品的脱硫实验。系统地研究了氧气流速、反应温度、硫含量对脱硫效率的影响，筛选出最佳反应条件，同时考察了空气作为氧化剂用于油品脱硫的可行性。结果表明，当初始硫含量为350 μg·g-1，氧气流速为90 ml·min-1，反应温度为75℃，催化剂用量占模拟油品质量的1%，反应时间60 min，二苯并噻吩（DBT）的转化率可达74%。此外，通过重复利用实验证明催化剂有良好的再生活性。

| Abstract: | A heterogeneous catalyst, chromium terephthalate metal organic framework (MIL-101) encapsulated phosphotungstic acid (HPW), HPW@MIL-101,was prepared by one step method. And then it was used as catalyst in oxidative desulfurization system in which O2 acted as oxidant for the removal of dibenzothiophene (DBT). The effects of oxygen flow rate, sulfur content and reaction temperature on the desulfurization were studied. The results show that the DBT conversion is up to 74% for 60 min under the optimal reaction condition (sulfur content:350 μg·g-1, oxygen flow rate:90 ml·min-1, the amount of catalyst:1% the mass of normal octane; reaction temperature:75℃). The DBT conversion doesn't decrease obviously, after reused for three times with this catalyst. And it is possible to use air as green oxidant in desulfurization. |
