Polymeric nanoporous materials fabricated with supercritical CO2 and CO2-expanded liquids.
Both academia and industries have put great efforts into developing non-destructive technologies for the fabrication of polymeric nanoporous materials. Such non-destructive technologies developed with supercritical CO2 (scCO2) and CO2-expanded liquids (CXLs) have been attracting more and more attention because they have been demonstrated to be green and effective media for porous polymer prepar...
متن کاملAdsorption of Ethyl Acetate onto Modified Clays and Its Regeneration with Supercritical Co2
Modified clays were used to remove ethyl acetate from aqueous solutions. These clays were regenerated using supercritical CO2. Structural changes in the montmorillonite clay after treatment with quaternary amines were studied. The surface properties of the modified clay changed from highly hydrophilic to highly organophilic. The clay was regenerated by percolation of a stream of CO2 through the...

Adsorption of Organics on Msc5a in Supercritical Co2, Molecular Simulation
Chromatographic measurements were made for the adsorption of benzene, toluene and m-xylene on molecular sieving carbon (MSC) in supercritical fluid CO2 mixed with organics. Supercritical chromatograph packed with MSC was used to detect pulse responses of organics. Adsorption equilibria and adsorption dynamics parameters for organics were obtained by moment analysis of the response peaks. Depend...
متن کاملMathematical Model of Supercritical Co2 Adsorption on Activated Carbon Applied to Adsorption Scale-up
A general mathematical model for supercritical CO2 adsorption on activated carbon have been developed. Adsorption curves obtained with a laboratory plant (adsorber of 10 mL) have been adjusted with this model and the results have been extrapolated to adjust the breakthrough curves obtained with a pilot plant (adsorber of 1L). The proposed model is general and takes into account equilibrium (ads...
