The study of multicomponent adsorption is critical to understand processes in conditions typically found in industrial environments. Nevertheless, single component analyses are most often performed due to the commercial availability of instruments for the collection of single component isotherms as well as the ease in operation. With the release of MicroActive v6.0, multicomponent adsorption isotherms can be predicted using ideal adsorbed solution theory (IAST). IAST is a predictive technique developed by Myers and Prausnitz in 1965. It is used to predict mixed gas adsorption behavior from single component isotherms. IAST predictions have proven to be in good agreement with experimental results for a variety of binary gas systems including, methane/ethane in BPL carbon, Xe/Kr in zeolite NaA, and propane/propylene in HKUST-1 (Furmaniak, et. al., pccp, 2015). This webinar will feature the newly incorporated IAST predictions in MicroActive for predicting adsorption of binary mixtures of CO2, CH4, and C2H6 in three microporous carbons.
