Pure and Binary Net Adsorption of CH4, CO2 and C2H4

摘要

The net adsorption thermodynamic framework was introduced by Gumma and Talu (Langmuir 2010, 26(22), 17013‐17023). Net adsorption fundamentally differs from excess and absolute adsorption by the placement of Gibbs dividing surface which is necessary to quantify any adsorption process. Net adsorption is a natural choice for microporous solids. It removes any ambiguity in adsorption phenomena by circumventing questionable measurements and quantities such as; 1) solid volume necessary for excess adsorption (typically based on non‐adsorbing helium assumption), and 2) pore volume necessary for absolute adsorption (typically based on liquid density assumption in micropores).
