Mixed Matrix Carbon Molecular Sieve and Alumina (CMS-Al2O3) Membranes
This work shows mixed matrix inorganic membranes prepared by the vacuum-assisted impregnation method, where phenolic resin precursors filled the pore of α-alumina substrates. Upon carbonisation, the phenolic resin decomposed into several fragments derived from the backbone of the resin matrix. The final stages of decomposition (>650 °C) led to a formation of carbon molecular sieve (CMS) structu...
متن کاملOn the Effective Permeability of Mixed Matrix Membranes
Mixed matrix membranes (MMMs) are attracting significant interest for pervaporation and gas separation applications. To better comprehend the impact of filler particles within polymer matrices, the species permeation mass transport was theoretically studied by numerical simulation using finite differences. The Fick’s second law of diffusion was solved for a three-dimensional MMM to obtain the c...
متن کاملGas Separation Properties of Mixed Matrix Membranes based on Polyimide and Graphite Oxide
In this work, three different graphene-based materials, namely graphite oxide (GrO), thermally reduced graphite oxide (T-RGrO) and ascorbic acid multi-phase reduced graphene oxide (AMP-RGO), were synthesized and used to produce mixed matrix membranes (MMM) based on Matrimid®5218 for as separation. From the samples produced, a complete set of characterization was performed including XRD, FTIR, T...
متن کاملInterior Modification of Nano-Porous Fillers to Fabricate High Performance Mixed Matrix Membranes
A new method is developed to enhance the gas separation properties of mixed matrix membranes (MMMs) by interior modification of an inorganic nano-porous particle. Ship-in-a-bottle (SIB), as a novel synthesis strategy, is considered to encapsulate a polyaza macrocyclic Ag-ligand complex into the zeolite Y, which is resulted in a new host-guest nano-composite. It is consequently incorporated into...
متن کاملPurified and Functionalized MWCNTs: Application In CO2/CH4 Separation Using Mixed Matrix Membranes
To fabricate a defect free and high performance mixed matrix membrane (MMM), one approach is the functionalization of inorganic nanofillers (as dispersed phase) in the organic polymer matrix (as continuous phase) to modify the interactions between two phases. For this purpose,, raw multi-walled carbon nanotubes (rMWCNTs) were purified by acid mixture (HNO3/H2SO<sub...
