dc.description.abstractNatural gas must be dehydrated before it can be transported and used, but conventional drying agents such as activated alumina or inorganic molecular sieves require an energy-intensive desiccant-regeneration step. We report a hydrolytically stable fluorinated metal-organic framework, AlFFIVE-1-Ni (KAUST-8), with a periodic array of open metal coordination sites and fluorine moieties within the contracted square-shaped one-dimensional channel. This material selectively removed water vapor from gas streams containing CO2, N2, CH4, and higher hydrocarbons typical of natural gas, as well as selectively removed both H2O and CO2 in N2-containing streams. The complete desorption of the adsorbed water molecules contained by the AlFFIVE-1-Ni sorbent requires relatively moderate temperature (~105°C) and about half the energy input for commonly used desiccants.
dc.description.sponsorshipResearch reported in this publication was solely performed at KAUST and was supported by KAUST funds, KAUST funding grants (CCF/1/1972-02-01, CCF/1/1972-8-01, and OSR-2017-CPF-3325), and Aramco. The data reported in the paper are presented in the main text and the supplementary materials. Crystal structures of the as-synthesized AlFFIVE-1-Ni, the dehydrated AlFFIVE-1-Ni, AlFFIVE-1-Ni (rehydrated), AlFFIVE-1-Ni·1.48H2O·0.26CO2, and FeFFIVE-1-Ni are available free of charge from the Cambridge Crystallographic Data Centre (CCDC) under reference nos.
