Iast selectivities
WebbTwo possibilities: A) You calculate the selectivy from the Langmuir Equation, which is a constant and does not vary with the component pressures: S = (q1*b1)/ (q2*b2) B) You …WebbThe adsorption selectivity, S, for binary mixtures of components 1 and 2 is defined as: (2) where q1 and q2 are the molar loadings (in mmol/g) and p1 and p2 are the partial pressures of species 1 and 2 (in mbar), respectively. IAST is analogous to Raoult's law and assumes an ideal solution of the gas components 1 and 2

Webb6 dec. 2024 · While IAST works well for mixtures with weak lateral interactions, CH 4 /N 2 and CO/N 2, the deviations are large for mixtures with stronger lateral interactions, CO 2 /N 2 and CO 2 /CH 4. Motivated by the theory of London dispersion forces, we propose use of the geometric mean instead of the arithmetic mean and achieve substantial improvements.Webb1 jan. 2024 · The two kinds of SMOFs can efficiently separate Xe/Kr with ideal adsorbed solution theory (IAST) selectivity values of 6.9 and 6.7 under 298 K and 1.0 bar, respectively.
