461715 Bio-Alcohol Recovery from Aqueous Solutions with a Resistant and Formulated MOF Material
The ZIF-8 MOF material offers perspectives for the economical and low energy intensive production of biobutanol. A key aspect towards the implementation of ZIF-8 into an actual separation process is its formulation into a resistant structure while maintaining its promising features. As a consequence, in this work, various resistant pellets were produced, by combining polymer binders with ZIF-8 powder under different conditions. The stability of the pellets under acid-base, hydrothermal and long-term storage (3 years) was tested as well as their adsorptive properties under dynamic and static conditions in liquid and vapor phase. Furthermore the pellets were characterized with argon and mercury porosimetry. The results of these different experiments will be shown in this presentation and compared to the binder-free ZIF-8 pellets and powder material. It will be demonstrated that the formulation of the ZIF-8 material resulted in resistant pellets without altering its promising adsorptive properties.
