Recent Developments in High-Performance Membranes for CO2 Separation

Composite electrolyte membranes for high temperature CO2 separation

Amembrane device that can selectively separate CO2 at temperatures exceeding 600 ◦C has been demonstrated. The membrane can be made from a composite material made of a molten carbonate electrolyte eceived in revised form 24 October 2010 ccepted 28 October 2010 vailable online 3 November 2010

Recent developments in high-temperature proton conducting polymer electrolyte membranes

Progress in the area of proton conducting polymer electrolyte membranes is intimately linked with the development of polymer electrolyte membrane fuel cells, and is today largely driven by the insufficient properties of humidified Nafion membranes at temperatures above 100 8C. Recent developments in the field include new ionomers and hybrid membranes containing inorganic nanoparticles to contro...

Synthesis of PIL membranes for CO2 separation

Carbon dioxide (CO2) can be commonly found in natural gas streams, biogas, flue gas and product of coal gasification[1]. The presence of CO2 and other acid gases reduce the thermal efficiency and make the gas streams become acidic and corrosive, which in turn reduces the possibilities of gas compression and the transport within the transportation systems[2]. Membrane separation is a promising t...

AlPO-18 membranes for CO2/CH4 separation.

The synthesis of reproducible and continuous AlPO-18 membranes is demonstrated. The separation performance of these membranes for equimolar CO(2)/CH(4) gas mixtures is presented. The AlPO-18 membranes displayed CO(2) permeances as high as ~6.6 × 10(-8) mol m(-2) s Pa with CO(2)/CH(4) separation selectivities in the ~52-60 range at 295 K and 138 kPa.
