摘要
采用水热法合成新型多孔材料MOF-199,利用XRD、77K下N2吸附等温线和SEM表征其结构.运用固定床吸附穿透曲线考察了模型燃油类型对MOF-199吸附分离噻吩的影响.结果表明,MOF-199在脂肪和芳香模型油中的饱和吸附容量分别为1.96wt%和1.85wt%,超过相关文献报道.MOF-199在含溶解水和纯混合模型油中噻吩硫的饱和吸附容量分别为2.15wt%和1.62wt%,脱硫吸附容量降低了25%.运用活性炭分层填装吸附柱技术可使MOF-199饱和吸附容量达到2.12wt%.
Novel porous material MOF-199 was synthesized by hydrothermal synthesis and characterized by XRD,SEM analyses and N2 adsorption at 77 K. Types of simulated oils on adsorptive separation thiophene sulfur was stuied by fixed adsorption bed breakthrough curves. It was found that the saturation capacity of sulfur element for MOF-199 was 1.96wt% and 1.85wt% in the aliphatic and aromatic simulated oil,respectively,higher than those previously reported results. The saturation capacity of sulfur element for MOF-199 was 2.15wt% and 1.62wt% in mositure aliphatic and aromatic simulated oil mixture. However,when moisture existed,the capacity dropped to 1.62wt%,which decreased by 25% compared with dry oil mixture. Moreover,the saturation capacity of 2.12wt% can be obtained by laying actived carbon technique.
