High retention volume covalent organic polymer for xenon capture:Dynamic separation of Xe and Kr
文献摘要：
Xenon capture and Xe/Kr separation are important processes in industry.For instance,Xe/Kr separation is an indispensable step in recycle and treatment of nuclear fuel emission.Among different separation methods,selectively adsorb gas molecules using porous materials is a promising way to reduce the high energy consumption in traditional cryogenic distillation.However,many reported adsorbents still face the challenges of:i)poor separation property at low Xe/Kr concentrations;ii)insufficient retention volumes,which influence the viability of whole process.In this work,we present a stable covalent organic polymer,i.e.,COP-14,showing promising potential for Xe/Kr separiton.In dynamic breakthrough experiments,COP-14 successfully separates low concentration Xe(350 ppm)and Kr(35 ppm)from target gas mixtures.Meanwhile,the xenon retention volume per gram(1700 mL g-1 at 298 K)of COP-14 in dynamics absorption process achieves 3.8 times of benchmark active carbon.The good performance of the newly devloped COP-14 mainly from its rich nitrogen sites and suitable pore size with xenon molecues.The promising results of COP-14 on Xe/Kr separation in this work provide a promising way for designing efficient Xe/Kr separation mateirals.
