TL;DR: Control over pore chemistry and size in metal coordination networks with hexafluorosilicate and organic linkers for the purpose of preferential binding and orderly assembly of acetylene molecules through cooperative host-guest and/or guest-guer interactions is reported.

TL;DR: In this article, the adsorption equilibrium selectivity was calculated from the ratio of Henry's constants, and the adsorbent selection parameter for pressure swing adaption was determined gravimetrically at 298 K and elevated pressures (14 bar for CO2 and 100 bar for CH4).

TL;DR: In this article, a number of different separation strategies can be employed to achieve the desired desired separation performance using microporous metal-organic frameworks (MOFs), including selective binding with the metal atoms of the framework, exploiting differences in molecular packing efficiencies within the ordered pore structures, utilizing selectivities based on the framework flexibility and gate-opening mechanisms, and molecular sieving.

TL;DR: The adsorption kinetic measurements suggest that the diffusivities of CO(2) and CH(4) on Mg-MOF-74 were comparable to those on zeolite 13X and the pressure-dependent equilibrium selectivity of CO (2) over CH (4) (q(CO2)/q(CH4)) in the M g-MOf-74 adsorbent showed a trend similar to that of zeolites 13X.

TL;DR: The relatively high values of adsorption selectivity suggest that it is feasible to separate ethylene/ethane, propylene/propane, and propylene-ethylene pairs in a vacuum swing adsorptive process using Mg-MOF-74 as an adsorbent.
