DEVELOPMENT OF ENHANCED MIXED MATRIX MEMBRANES BY USING ALKANOLAMINE SOLUTION FOR C02/CH4 SEPARATION
Poor performance of mixed matrix membranes (MMMs) is due to agglomeration of fillers and weak adhesion between the fillers and the polymer matrix. The main objective of this study is to synthesize enhanced MMM consisting polyethersulfone (PES), carbon molecular sieve (CMS) and di-ethanolamine (DE...

| Summary: | Poor performance of mixed matrix membranes (MMMs) is due to agglomeration
of fillers and weak adhesion between the fillers and the polymer matrix. The main
objective of this study is to synthesize enhanced MMM consisting polyethersulfone
(PES), carbon molecular sieve (CMS) and di-ethanolamine (DEA) which is having
high carbon dioxide (C02 ) affinity for improvement of membrane morphology and
performance. Various loadings ofCMS (10-30 wt. %) and concentrations ofDEA (5-
\5 wt. %) was incorporated into PES sol to synthesize enhanced MMMs. The
membranes morphology, physicochemical, thermal and mechanical properties were
analysed systematically. The performance of these membranes was evaluated and
measured in terms of permeance and selectivity. The morphological evaluation
showed the dense. non-porous structure. in which the CMS and DEA were uniformly
distributed within the polymer matrix. |
