We present a systematic study of metal-organic frameworks (MOFs) for the storage of oxygen. The study starts with grand canonical Monte Carlo simulations on a suite of 10,000 MOFs for the adsorption of oxygen. From these data, the MOFs were down selected to the prime candidates of HKUST-1 (Cu-BTC) and NU-125, both with coordinatively unsaturated Cu sites. Oxygen isotherms up to 30 bar were measured at multiple temperatures to determine the isosteric heat of adsorption for oxygen on each MOF by fitting to a Toth isotherm model. High pressure (up to 140 bar) oxygen isotherms were measured for HKUST-1 and NU-125 to determine the working capacity of each MOF. Compared to the zeolite NaX and Norit activated carbon, NU-125 has an increased excess capacity for oxygen of 237% and 98%, respectively. These materials could ultimately prove useful for oxygen storage in medical, military, and aerospace applications.

“…UiO-66 was synthesized as reported by Peterson et al (2013b), i.e., 19.068 mmol of zirconium (IV) chloride and 19.068 mmol of 1,4-benzenedicarboxylic acid were mixed in 742 mL of dimethyl formamide (DMF) at room temperature in a glass beaker. The resulting mixture was divided in equal parts into three 500 mL glass jars.…”

“…On the basis of their results, it was concluded that pelletization leads only to a small reduction in sorbent capacity [23]. It should also be noted that most recently, a similar study was carried out by Peterson et al, whereby the effect of pelletization pressure on the physical and chemical characteristics of the metal-organicframeworks Cu 3 (BTC) and UiO-66 was investigated [24]. These MOFs were pressed at 1000 and 10000 psig and the authors showed that both CuBTC and UiO-66 could tolerate these pressures and be engineered into pellets, although some degradation in porosity was observed for these materials as well.…”

Jones, Shaping aminebased solid CO 2 adsorbents: effects of pelletization pressure on the physical and chemical properties, Microporous and Mesoporous Materials (2014), doi: http://dx.ABSTRACT: Amine-based solid adsorbents are promising candidates for the separation of CO 2 from dilute gas streams. Here we report the effect of pelletization pressure on the physical and chemical properties of an array of supported amine adsorbents, based on mesoporous silica and γ-alumina supports. The virgin powders based on poly(ethyleneimine) (PEI) and 3-aminopropyltrimethoxysilane (APS) functionalized oxides are pressed at 1000 and 5000 psig pressure to form self-supporting pellets and their physical and chemical properties are compared.No change in chemical structure of the adsorbents is observed after pelletization, though the porosity of each material changes to some degree. Of the three mesoporous supports examined in this study, the commercial porous silica was the most stable support for both class 1 and class 2 adsorbents, whereas lab synthesized mesoporous SBA-15 silica and lab synthesized mesoporous γ-alumina are found to be the least stable supports for class 1 and class 2 adsorbents, respectively. The CO 2 uptake results show a significant drop in equilibrium capacity for the pellets pressed at 5000 psig, regardless of the support used, while the 1000 psig pellets retain their capacity and show comparable performance to their powder counterparts. CO 2 2 breakthrough experiments suggest an increase in mass transfer resistance for the pellet samples as compared with virgin powders, resulting in the dispersion of the concentration fronts during CO 2 breakthrough using a fixed bed. These findings suggest that shaping solid supported amine adsorbents into binderless pellets requires pressing the powders at low to moderate pressures to ensure that these materials retain their performance in processes that require pelletized samples.
