“…C 3 H 6 is an extremely significant building block for various valuable chemicals, including polypropylene, isopropyl alcohol, and propylene oxides [100,101] . Nevertheless, the purification of C 3 H 6 is considered a challenging task in industrial separation in terms of the high affinity between C 3 H 6 and C 3 H 8 [2,102,103] . Generally, cryogenic distillation is the prevailing approach for C 3 H 6 /C 3 H 8 separation in industry, which is a mature yet extremely energy and cost‐intensive process [104,105] .…”

Due to facile designability and versatile nanospace, metal-organic frameworks (MOFs) have been considered as promising membrane materials. Compared to the mixed matrix membranes that incorporated with MOF particles, the polycrystalline MOF membranes demonstrates significant advantages in maximum utilizing the crystalline nanospace, and thus yielding a fruitful of achievements in the last twenty years. Although some reviews have summarized the development of MOF-based membranes, the theoretical framework for oriented design and preparation of polycrystalline MOF membranes for highly efficient separation of light hydrocarbons remains in infancy. Herein, in this review, the fabrication strategies of polycrystalline MOF membranes and the corresponding performance in the separation of light hydrocarbons were classified and summarized. Particularly, the MOF membranes with global and local dynamics have been proposed as an interesting topic promoted performance.

“…In the past decades different processes have been developed and realized to ensure the basic supply of propene. The most prominent processes using propane as a feedstock to produce propene directly are the Oleflex Process, Catofin Process, STAR Process, and Linde Process [2][3][4]. These processes share a requirement for catalyst regeneration after a limited period of operation due to coke formation, which leads to fast catalyst deactivation.…”

A Pt‐ZSM5 catalyst, coked during propane dehydrogenation and regenerated with lean air, was studied by various in‐situ and ex‐situ methods. A newly developed isothermal ceramic flat‐bed reactor with inert surfaces is described and used in the experiments. Comparative measurements successfully demonstrated that temperature alone has no effect on the catalyst and that changes in conversion and selectivity are due to coke formation. Nuclear magnetic resonance (NMR) studies using triphenylphosphine probe molecules of activated and deactivated samples showed the localization of the Pt clusters inside and outside the zeolite pores. It was shown that the Pt clusters are mainly located inside the zeolites and that the mobilization of Pt by contact with oxygen leads to permanent aging.
