Adsorption and diffusion of carbon dioxide on metal−organic framework (MOF-5) / Zhenxia Zhao in Industrial & engineering chemistry research, Vol. 48 N° 22 (Novembre 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 22 (Novembre 2009) . - pp. 10015–10020 Titre : Adsorption and diffusion of carbon dioxide on metal−organic framework (MOF-5) Type de document : texte imprimé Auteurs : Zhenxia Zhao, Auteur ; Zhong Li, Auteur ; Y. S. Lin, Auteur Année de publication : 2010 Article en page(s) : pp. 10015–10020 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Microporous  metal−organic  framework  Adsorption  equilibrium  Diffusion Résumé : Adsorption equilibrium and diffusion of CO2 on microporous metal−organic frameworks (MOF-5, or IRMOF-1) crystals were experimentally studied by the gravimetric method in the pressure range up to 1 atm. The MOF-5 crystal cubes of about 40−60 μm in sizes were synthesized by the solvothermal method. Freundlich adsorption isotherm equation can fit well CO2 adsorption isotherms on MOF-5, with isosteric heat of adsorption of about 34 kJ/mol. Diffusion coefficient of CO2 in the MOF-5 is in the range of 8.1−11.5 × 10−9 cm2/s in 295−331K with activation energy of 7.61 kJ/mol. MOF-5 offers attractive adsorption properties as an adsorbent for separation of CO2 from flue gas.
