选择性或容量增强的新材料的发现将促进吸附的应用，特别是在环境控制方面。特别提到，可以制备具有不同定制性能的金属有机框架（MOF）以实现所需的分离。为了促进MOF材料的工业应用，规模化和工艺设计还必须得到充分的发展。本文报道了Cu-MOF挤出物对甲烷和二氧化碳的吸附平衡数据。观察到的最重要的性质是CO(2)的高容量和等温线的小非线性。在这种情况下，这种吸附剂可用于沼气升级，以产生生物甲烷并减少化石燃料CO(2)。
The discovery of new materials with enhanced selectivity or capacity will boost adsorption applications, especially for environmental control. In particular, it was mentioned that metal-organic frameworks (MOF) with different tailored properties may be prepared for desired separations. To promote industrial application of MOF materials, up-scaling and process design still must be completely developed. In this work, we report adsorption equilibrium data of methane and carbon dioxide on Cu-MOF extrudates. The most important properties observed are the high-capacity for CO(2) and the small nonlinearity of the isotherms. In this context, this adsorbent can be used for biogas upgrading to produce biomethane and reduce fossil-fuel CO(2).
