Applications of zeolite membranes in separation, chemical sensors, and catalytic membrane reactors have led to extensive studies on their fabrication. To date, mainly silicatebased zeolite membranes of the structure types MFI, DDR, LTA, and FAU have been synthesized on different substrates and evaluated for singleor multiple-gas permeation. Routes for the synthesis of zeolite membranes can be b...

carbon membrane can be produced using a wide variety of polymer precursor materials via heat treatment process. a general concept route of precursor selection-preparation-modification-performance analysis platform for the carbon membrane has been proposed to promote the development of carbon membrane material for a wide range of application. the current review considers the recent progress of c...

Separation of carbon dioxide and methane is an important issue in upgrading low-quality natural gas. Adsorption equilibria and kinetics of CO(2) and CH(4) on a copper metal-organic framework (MOF), Cu(hfipbb)(H(2)hfipbb)(0.5) [H(2)hfipbb=4,4'-(hexafluoroisopropylidene) bis(benzoic acid)], were investigated to evaluate the feasibility of removing CO(2) from CH(4) in a pressure swing adsorption p...

The separation of H2O vapor from (hydrogen-rich) gaseous streams is a topic increasing interest in the context CO2 valorisation, where situ water removal increases product yield and catalyst stability. In this work, composite alumina carbon molecular sieve membranes (Al-CMSM) were prepared phenolic resin solutions loaded with hydrophilic boehmite (γ-AlO(OH)) nanosheets (0.4–1.4 wt. % solution) ...

Electrothermal Swing Adsorption (ESA), or Joule-Effect heating of adsorbents in a cyclic adsorption process, is an energy-efficient technology on which to base a regenerative protective filter system. In an attempt to define the performance envelope of ESA systems, we evaluated three different ESA media: Activated carbon fiber cloth (ACFC), Carbon Fiber Composite Molecular Sieve (CFCMS), and Mi...
