摘要 燃料油中含硫化合物的脱除一直是人们关注和研究的热点。采用溶剂热法原位合成磁性金属有机骨架复合材料Fe3O4-COOH@MIL-101,并利用XRD、SEM等技术对其进行表征。基于动态吸附实验,利用GC法分析检测,考察该复合材料对模型油中两种噻吩类硫化物苯并噻吩、二苯并噻吩的吸附脱硫效果。实验结果表明,Fe3O4-COOH@MIL-101复合材料兼具MIL-101和磁性微球的双重优异性能,Fe3O4-COOH@MIL-101复合材料对苯并噻吩和二苯并噻吩的平衡吸附量可以达到7.99 mg/g和24.60 mg/g,具有较快的吸附反应动力学且符合动力学二级模型。

Abstract: The desorption of sulfur compounds in fuel oil has been the focus of attention and research. Magnetic metal-organic framework composites Fe3O4-COOH@MIL-101 was prepared through solvothermal in situ, and it was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), etc. Based on dynamic adsorption experiments, GC (gas chromatography) was used to investigate the effect of the material on the desulfurization of two kinds of thiophene compounds, benzothiophene (BT) and dibenzothiophene (DBT). The results show that Fe3O4-COOH@MIL-101 composite materials have excellent properties of both MIL-101 and magnetic microspheres. The equilibrium adsorption capacity of Fe3O4-COOH@MIL-101 on the BT and DBT can reach 7.99 mg/g and 24.60 mg/g, respectively. It has a faster adsorption reaction dynamic and obeys second-order kinetics model.
