摘要:
常温法合成了沸石咪唑酯骨架材料ZIF-8和ZIF-67,用 XRD、 SEM和BET测试手段对所合成的样品进行了表征。测定了正己烷、2-甲基戊烷单组份分别在ZIF-8和ZIF-67吸附材料上的吸附等温线,结果发现各组份在ZIF-8上的静态饱和吸附量均高于ZIF-67; 通过固定床动态吸附穿透实验测定了正己烷/二甲基戊烷混合液在ZIF-8上的连续流出穿透曲线,结果表明,ZIF-8对正己烷具有明显的吸附选择性,总压1.0 MPa、进料浓度比1:1时ZIF-8对正己烷的动态吸附量为0.40 g·g-1、正己烷/二甲基戊烷分离系数为5.71。
Abstract:
Zeolitic imidazolate frameworks ZIF-8 and ZIF-67 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 breakthrough curves of n-hexane/2-methylpentane mixture absorbed on ZIF-8 were obtained by continuous dynamic adsorption experiments. The results show that ZIF-8 exhibits a higher selectivity and adsorption capacity for n-hexane.At the total pressure of 1.0 MPa and feed concentration ratio of 1:1, the dynamic adsorption capacity of ZIF-8 for n-C6 is 0.40 g·g-1, the separation factor is 5.71.
