Quasi-Orthogonal Configuration of Propylene within a Scalable Metal-Organic Framework Enables Its Purification from Quinary Propane Dehydrogenation Byproducts.

ABSTRACT: Propylene production via nonoxidative propane dehydrogenation (PDH) holds great promise in meeting growing global demand for propylene. Effective adsorptive purification of a low concentration of propylene from quinary PDH byproducts comprising methane (CH₄), ethylene (C₂H₄), ethane (C₂H₆), propylene (C₃H₆), and propane (C₃H₈) has been an unsolved academic bottleneck. Herein, we now report an ultramicroporous zinc metal-organic framework (Zn-MOF, termed as 1) underlying a rigid one-dimensional channel, enabling trace C₃H₆ capture and effective separation from quinary PDH byproducts. Adsorption isotherms of 1 suggest a record-high C₃H₆
