摘　　要：采用水热法合成出金属有机骨架化合物MOF-14,基于固定床动态吸附实验,考察了室温下MOF-14对模型油中噻吩及苯并噻吩的脱除效果,并经溶剂甲苯洗涤对吸附剂进行再生。结果表明,MOF-14对模型油中噻吩和苯并噻吩的饱和吸附容量分别为2.02%,0.53%;吸附剂再生后对模型油中苯并噻吩的吸附饱和容量为0.53%,再生率达到100%。Metal - organic framework compound MOF - 14 was synthesized under hydrothermal con- ditions. Based on the fixed bed dynamic absorption test, the effects of removing thiophene and benzothio- phene from model oil at room temperature by MOF- 14 were investigated, and the adsorbent was reactivated through solvent toluene washing. The re- sults showed that the saturated adsorption capacities of thiophene and benzothiophene on MOF- 14 were 2.02% ,0.53% respectively. The saturated adsorp- tion capacity of benzothiophene on the reactivated MOF-14 was 0.53%, and the reactivation rate reached 100%.
