Characterization of porous materials by gas adsorption at ambient temperatures and high pressure

Article Abstract:

Carbon dioxide is a more sensitive probe of the microporosity of active carbons than methane or nitrogen at ambient temperatures due to near critical capillary condensation in graphite micropores. PSDs predicted from carbon dioxide adsorption isotherms can be used to estimate the adsorption isotherms can be used to estimate the adsorption isotherms of methane and nitrogen on the same material with reasonable accuracy.

Adsorption mechanism of carbon dioxide in faujasites: Grand canonical Monte Carlo simulations and microcalorimetry measurements

Article Abstract:

The interactions between carbon dioxide and various types of faujasite surfaces are described with the help of Grand canonical Monte Carlo (GCMC) molecular simulations and adsorption microcalorimetry measurements. The force field was revealed to be very transferable as it allowed accurate reproduction of the microcalorimetry data in three different faujasite forms, namely, DAY, NaY and NaLSX.

Gas adsorption in active carbons and the silt-pore model 2: Mixture adsorption prediction with DFT and IAST

Article Abstract:

A fast density theory (a "slab-DFT") and the polydisperse independent ideal silt-pore model is used to predict gas mixture adsorption in active carbons. The methods used are at least as accurate as IAST for the relatively simple gas mixtures and have the advantage of much greater versatility.
