摘　　要：将金属有机骨架材料应用于燃油深度脱硫研究。采用水热法合成了金属有机骨架材料MOF-5,利用XRD、N2吸附和SEM等技术对其结构进行了表征。通过测定固定床吸附穿透曲线,考察了模型燃油类型对MOF-5吸附分离噻吩效果的影响。结果表明,MOF-5对硫化物的吸附容量超过了文献报道;在脂肪油中其穿透容量和饱和容量质量分数分别为0.90%和1.92%,在芳香模型物质中其穿透容量和饱和容量质量分数分别为0.64%和1.72%。通过采用与活性炭分层填装吸附柱技术,解决了溶解水对脱硫的影响,为吸附脱硫技术提供了新思路。A novel method for the deep desulphurization of fuel products was investigated by using the metal organic framework material MOF-5 as an adsorbent.MOF-5 was synthesized hydrothermally and its structure was characterized by means of XRD,SEM and N2 adsorption.The desulphurization performance of MOF-5 was tested in terms of breakthrough curves with the simulated oils at room temperature.The results showed that the adsorbent MOF-5 possesses quite large sulfur capacity,even larger than those reported previously in literature.The adsorbent breakthrough capacity and saturation capacity for sulfur component were 0.90% and 1.92% in the aliphatic oil,and 0.64% and 1.72% in the aromatic oil,respectively.The negative effect of moisture on the desulphurization performance was eliminated by packing it with the activated carbon adsorbent together,which provides a new way for the development of the adsorptive desulphurization process.
