摘　　要：分离过程是化学工业的关键步骤,也是能耗和物耗最为集中的过程,占全部工业能耗的近50%。特别是乙烯、乙炔和丙烯等大宗基础化学品的生产过程,当前仍主要依赖于深冷精馏等高耗能分离技术,亟待发展高效分离技术。吸附和膜分离等相关技术的进步有望显著降低分离过程能耗。The trade-off between adsorption capacity and selectivity of porous materials has been identified as a major challenge towards efficient gas separation/purification through physisorption. The research from Cui et al. address this daunting challenge by developing a new strategy that control over pore chemistry and pore size in hybrid porous materials enables the exploitation of supramolecular chemistry of gases to achieve both high capacity and selectivity, and sets new benchmarks for acetylene separation from ethylene.
