Abstract 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.
