己烷在沸石咪唑酯骨架材料ZIF-8、ZIF-67上的吸附性能研究
Adsorption Separation of Hexane on ZIF-8 and ZIF-6 7
摘要
Abstract
Zeolitic imidazolate frameworks ZIF-8 and ZIF-6 7 were synthesized at room temperature.The two samples were characted by XRD,SEM and BET.The single component adsorption equilibrium isotherms for n-hexane、2-methylpentane on the two ZIF materials were measured.The results show that the static adsorbed amount of n-hexane and 2-methylpentane on ZIF-8 is higher than that on ZIF-67.The break-through curves of n-hexane/2-methylpentane mixture absorbed on ZIF-8 were obtained by continuous dy-namic adsorption experiments.The results show that ZIF-8 exhibits a higher selectivity and adsorption ca-pacity for n-hexane.At the total pressure of 1.0MPa and feed concentration ratio of 1∶1,the dynamic ad-sorption capacity of ZIF-8 for n-C6 is 0.40g·g-1 ,the separation factor is 5.71.关键词
