RT Journal Article T1 Molecular Simulation Investigation into the Performance of Cu-BTC Metal Organic Frameworks for Carbon Dioxide-Methane Separations A1 Gutiérrez Sevillano, Juan José A1 Caro Pérez, Alejandro A1 Dubbeldam, David A1 Calero, Sofía K1 Zeolites K1 Molecular simulation K1 Adsorption K1 Diffusion AB We report a molecular simulation study for Cu–BTC metal–organic frameworks as carbon dioxide–methane separation devices. For this study we have computed adsorption and diffusion of methane and carbon dioxide in the structure, both as pure components and mixtures over the full range of bulk gas compositions. From the single component isotherms, mixture adsorption is predicted using the ideal adsorbed solution theory. These predictions are in very good agreement with our computed mixture isotherms and with previously reported data. Adsorption and diffusion selectivities and preferential sitings are also discussed with the aim to provide new molecular level information for all studied systems.
