Seeking to exploit the differences in N2 and O2 desorption kinetics discussed above, we explored conditions under which it would be possible to separately isolate the adsorbed N2 and O2. We found that it is indeed possible to desorb the majority of the bound N2 from the material at 25 °C under simulated vacuum with a He purge, after which point high-purity O2 can be isolated from the material (containing <0.5% N2 based on analysis of the stream composition using gas chromatography) by ramping the temperature to 50 °C (Figure ). Desorption of both N2 and O2 could also be conducted entirely at 25 °C, albeit with relatively sluggish kinetics for complete O2 desorption, indicating a tradeoff between desorption rates and thermal input for regeneration (Figure ).
