Mg-MOF-74/Polyvinyl acetate (PVAc) mixed matrix membranes for CO2 separation
Original language description
In this study, Mg-MOF-74 crystals were synthesised in order to prepare polymer/Mg-MOF-74 mixed matrix membranes (MMMs) for CO2/CH4 separation. Activation temperature and time of the Mg-MOF-74 crystals were determined in order to enhance the performance of polymer/Mg-MOF-74 mixed matrix. The Mg-MOF-74 crystals were then incorporated into polyvinyl acetate (PVAc) matrix to form dense MMMs by a solvent-casting method. After the structural characterisation of the prepared membranes, their CO2/CH4 separation properties were determined by measuring mixed gas permeabilities at 6 and 15 bar with a Wilke-Kallenbach method at steady-state. SEM image of MMM showed there were no visible voids at the MOF/polymer interface. The highest BET area of Mg-MOF-74 crystals was measured when activiation was performed at 150 °C for 24 h under vacuum. Mixed gas permeability measurements of the membranes showed that both CO2 permeability and selectivity were improved with the increasing amount of MOF suggesting strong adsorption selectivity of Mg-MOF-74 for CO2. Activation time of Mg-MOF-74 crystals influenced the permeability and selectivity of MMMs. Incorporation of Mg-MOF-74 helped reducing the effect of plasticization. © 2019 Elsevier B.V.
