Metal Organic Framework Adsorbent for Biogas Upgrading

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 CO2 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 CO2.
