摘要: 以NaY分子筛为载体,CuCl2为铜源,加入还原剂葡萄糖,在温和条件下制备CuCl/NaY吸附剂,通过变压吸附考察了该吸附剂对CO的吸附性能及CO/H2的分离性能。运用X射线衍射(XRD)、X射线光电子能谱(XPS)及程序升温还原(TPR)对吸附剂进行表征,结果表明采用葡萄糖还原法制备CuCl/NaY吸附剂,其制备条件温和,吸附剂表面的亚铜含量高,对CO的吸附及CO/H2的分离性能优越且稳定性好。

Abstract: The CuCl/NaY sorbents were prepared by impregnation method with copper chloride as metal precursor and glucose as reducing agent. The efficient amount of CO and the separation factor of CO/H2 were measured on sorbents. The microstructures of these sorbents were characterized by XRD 、XPS and TPR techniques. The results showed that the sorbents prepared using glucose as reducing agent had a higher amounts of Cu+ than those without glucose, which results in a better adsorption capability of CO and separation performance for CO/H2

Key words: CuCl/NaY, Glucose, Pressure swing adsorption, Carbon monoxide
