Feasibility Study of Gas Separation Membranes for Biohydrogen Separation

Polyurethane Mixed Matrix Membranes for Gas Separation: A Systematic Study on Effect of SiO2/TiO2 Nanoparticles

In this study, the effect of SiO2 and TiO2 nanoparticles on the gas separation performance of the polyurethane (PU) membranes has investigated. Polyurethanes were synthesized by bulk two step polym...

Plasticization of gas separation membranes*

For the investigation of the plasticizing effect of carbon dioxide on polymers used for gas separation membranes new experimental methods have been developed that measure the sorption kinetics as well as the dilation kinetics. Comparing dilation and sorption kinetics at low and elevated pressures gives information about different types of swelling behaviour depending on the pressure level. Volu...

Novel inorganic membranes for gas separation

A literature survey was performed to evaluate the state-of-the-art membrane systems for CO2/CH4 separation which is critical in the natural gas industry. The systems that were reviewed included zeolite, carbon, polymeric, mixed matrix, amorphous silica, and supported ionic liquid membranes. Supported ionic liquid CO2/CH4 selective membranes were synthesized in our laboratory by applying room te...

Polymeric Gas Separation Membranes: What Makes them Industrially more Attractive?

Synthesis and characterization of supported Phenolic resin/Carbon nanotubes Carbon membranes for gas separation

In this work, separation performance of supported carbon membranes produced from Novolac Phenolic resin as the main precursor and carbon nanotubes as nanofiller were investigated for separation of CO2 from N2 and CH4. Supports were produced by carbonization of Novolac Phenolic resin-activated carbon mixture, and selective layer was coated by dip coating of prepa...
