Separation & Environment

Adsorption processes for gas separation by selective adsorption using solid media, adsorbent, are established commercially as pressure swing adsorption (PSA), temperature swing adsorption (TSA), or vacuum swing adsorption (VSA). Recently, much effort have been devoted to develop ultra-porous materials, which can potentially meet the target of selective CO2 capture with rapid uptake and high selectivity for CO2, appropriate heat, mass transfer characteristics, stability in humid air, and mechanical properties. Nanoporous materials such as small pore Metal Organic Framework (MOF) are poised to play an important role in separation processes that can improve the environment. In addition to this, new materials to trap harmful molecules while allowing others to pass in applications trapping hydrocarbon emissions from automotive exhaust has to be designed.
