Membrane technology has been investigated for removing CO2 from mixtures with light
gases such as CH4, N2 and H2, and optimal membranes with high CO2 permeability and …

This paper reviews the material design and fabrication of a class of membranes where some
larger molecules can permeate faster than smaller ones, or so-called reverse-selective …

The field of polymer membrane design is primarily based on empirical observation, which
limits discovery of new materials optimized for separating a given gas pair. Instead of relying …

When polymeric membranes are employed to remove selectively one component from a
gaseous mixture, there is generally a trade-off between selectivity and permeability. Data …

The concept of free volume is useful for explaining aspects of the chain mobility and
permeability of polymers, even though its precise definition is subject to debate. Polymers …

The solubilities of He, H2, N2, O2, CO2, CH4, C2H6, C3H8, and n‐C4H10 were determined
at 35° C and pressures up to 27 atmospheres in a systematic series of phase separated …

Microporous materials have a great importance in catalysis, delivery, storage and separation
in terms of their performance and efficiency. Most microporous materials are comprised of …

Polyimides are a class of well‐known high‐performance polymers combined the excellent
mechanical, electrical, and thermal properties and widely applied in many high‐tech fields …

Carbon dioxide and nitrogen transport properties of cardo polymers, ie polyamide,
polycarbonate, polyimide, polysulfone and commercial polymers were investigated. These …

Conventional natural gas confronts the growing supply shortage due to the fewer formation
reserves. As a powerful replenishment, the nitrogen-rich unconventional natural gas, mainly …
