The use of ultramicroporous metal-organic framework material allows for efficient inverse separation of CO2 from C2H2 under ambient conditions, showing promise for industrial acetylene purification.
Removal of CO2 to purify CO2 /C2H2 mixtures through porous material is a more energy saving method compared with the traditional cryogenic distillation. Those CO2-selective adsorption porous materials are ideal for directly producing high-purity C2H2, especially allowing sieving separation with infinite selectivity but without sacrificing any uptake capacity. Here, we report an ultramicroporous metal-organic framework (MOF) [Cu(hfipbb)(H(2)hfipbb0.5)] (1), [H(2)hfipbb is 4,4'-(hexa-fluoroisopropylidene) bis(benzoic acid)] has been studied for inverse separation of CO2 from C2H2 under ambient conditions. This Cu-based MOF material was comprehensively demonstrated as an efficient CO2-selective adsorbent used for C2H2 purification by single-component adsorption isotherms, showing promise for industrial acetylene purification.
