Abstract
|
Pressure
swing adsorption (PSA) promises to be an economically viable separation of
CO2 from gas mixtures. An important step in developing efficient PSA
separations is to choose an adsorbent that balances selectivity and working
capacity. It is an optimization problem optimization involving the search of
properties of the adsorbent that offer the best trade-off between selectivity
and working capacity.
Researchers designed a method to optimize the properties of nonpolar adsorbents for PSA separation of CO2. They have extended the analysis to polar adsorbents. They employed a simplified model of the electric field generated by the solid obtain a better understanding of the effect of the geometry and the magnitude of the field on the adsorption behavior of the system. General rules about optimal adsorbents for CO2 adsorption in porous solid can be drawn, which can be used to define a strategy for the intelligent design of porous materials for CO2 separation applications. |
