Abstract
The mixed matrix membranes (MMMs) possess great potential for CO2 purification from natural gas (NG). By embedding a polymeric matrix with fillers such as metal organic frameworks, zeolites, carbons, silica, and other hybrid materials, they can achieve improved CO2 permeability and selectivity over the neat polymeric counterparts. The performance of MMMs largely depends on the quantity, quality, dispersion, interfacial interaction, and type of the fillers. This chapter reviews the recent progresses in MMMs for CO2 separation, with the focus on different families of fillers, their unique properties, separation performance, and selection criteria. It provides deep insights into the future development of MMMs toward industrial NG purification to trigger the Robeson’s upper bound limit.
