Influence of heat-treatment on CO2 separation performance of novel fixed carrier composite membranes prepared by interfacial polymerization

Preparation and characterization of small molecular amine modified PVAm membranes for CO2/H2 separation

“…Comparison of the CO 2 /H 2 separation performance of the PVAm-MEA/PS composite membrane with other membranes Polymeric amine membranes are including the membranes fabricated by PVAm or other polymers containing amine groups [3] and the membranes fabricated by the polymers containing amine groups and the cross-linking agents [34][35][36][37][38]. CO 2 permeance and selectivity of the membranes fabricated by the polymers containing amine groups are not high, because the amine group concentration in these membranes is low.…”

Basic Features and Techniques

“…As the reaction continues, the thickness of the polymer fi lm formed at the interface gradually increases, and this gradual enhancement of the thickness hinders the diffusion of the monomers. Because of the limited supply of reactants, the interfacial polymerization reactions are self -inhibiting, and thus an extremely thin fi lm down to 50 nm thickness may be achieved [74] . However, a continuous removal of the polymeric fi lm from the interface maintains the reaction.…”

A novel zeolitic imidazolate framework based mixed-matrix membrane for efficient CO 2 separation under wet conditions

“…CO 2 emissions into the atmosphere can be reduced by its capture and/or sequestration via economically viable processes [4,5] . As compared to other convenient processes ( e.g ., solvent scrubbing, adsorption, cryogenic distillation, microbial algae), gas separation technology using polymer-based mixed-matrix membranes (MMMs) has gained substantial importance due to their low capital and operating costs, improved efficiency, low energy requirement, uncomplicated function, flexible design, ease of scale up, and environmental kindliness [6][7][8][9][10][11][12][13] .…”
