Abstract
A series of supported membranes with zeolite FAU either as a thin layer or as powder in Matrimid as Mixed Matrix Membrane (MMM) have been prepared and evaluated in the H2/CO2separation. In addition to neat NaX membrane layers, we developed two novel composite materials, namely FAU/Matrimid®Mixed Matrix Membranes (MMMs) as well as NaX/Matrimid®multilayer/sandwich membranes, all of them supported by porous alumina plates. The influence of different pre-synthetic support modifications (APTES = 3-aminopropyltrietoxysilane, PDA = polydopamine) on the quality of neat supported NaX membranes grown as layer on these modified supports has been investigated studying the H2/CO2separation performance. It could be shown that NaX membrane layers grown on modified supports show an remarkably increased quality and correspondingly higher H2/CO2separation factors α (H2/CO2) (α = 8.0 for neat NaX, α = 8.9 for NaX/APTES and α = 10.3 for NaX/PDA). In the preparation of MMMs, the separation performance could be improved by ion exchanged Na-FAU powders. Exchanging the Na+of the as-synthesized NaX particles for metal ions with higher ionic potentials like Co2+, results in enhanced mixed gas separation factors α in the H2/CO2separation (NaX/Matrimid®MMM α = 4.0 and CoX/Matrimid®MMM α = 5.6).
