文摘

The previously introduced multiple equilibrium analysis (MEA), which produces equilibrium constants (K_i), capacities (n_i), and thermodynamic parameters (enthalpies, ΔH_i, and entropies, ΔS_i) of adsorption for each process, has been used to predict adsorption isotherms for N₂, CO, CH₄, C₂H₆, and SF₆ on one zeolitic (HZSM-5) and five carbonaceous (A-572, A-563, A-600, F-300, and BPL) solids. The adsorption of CO is best reproduced on each of the solids. In general, the adsorption of N₂ has been accurately predicted, while CH₄ and C₂H₆ are underpredicted and SF₆ is overpredicted. Previously reported high-pressure data for the adsorption of CH₄ on BPL was very accurately predicted. The application of the MEA prediction of adsorption behavior has quite a potential for a variety of applications. Adsorbents can be used for catalyst supports, gas separation, respiratory protection, environmental applications, and even have the potential for fuel storage capabilities. The prediction of adsorption performance will lead to a greater understanding of the fundamental interactions involved in these systems and will help create new and better systems.
